(We assume that these are the only disciplines in which part-time students at ABC College are enrolled and that an equal number of part-time students are enrolled in each of the disciplines.) Grouped distribution of continuous data tabulation frequencies is performed against a value group. Other well-known random sampling methods are the stratified sample, the cluster sample, and the systematic sample. Press ENTER. Create a systematic sample of 12 quiz scores. On your calculator, press Math and arrow over to PRB. To choose a simple random sample from each department, number each member of the first department, number each member of the second department, and do the same for the remaining departments. The data are discrete because the data can take on any value in an interval. Qualitative data are generally described by words or letters. What are the career options in the field of Statistics? However, in the real world age is often treated as a discrete variable because it makes more sense when collecting data and when reporting the results of a study. Solved CS State whether the data described below are - Chegg Over time, some continuous data can change. 3. When you have a numeric variable, you need to determine whether it is discrete or continuous. The registrar at State University keeps records of the number of credit hours students complete each semester. OB. The option "B" is correct i.e. Question: State whether the data described below are discrete or continuous, and explain why. Statistics and Probability questions and answers, state whether the data is continous or discrete The durations of Nominal and ordinal data can act as both discrete and continuous. Most statisticians use various methods of random sampling in an attempt to achieve this goal. Be aware that as you take data, your data may vary somewhat from the data someone else is taking for the same purpose. The table displays Ethnicity of Students but is missing the "Other/Unknown" category. A student interviews classmates in his algebra class to determine how many pairs of jeans a student owns, on the average. B. The departments are the clusters. This is important to know when we think about what the data are telling us. Quantitative data, on the other hand, is one that contains numerical values and uses a scope. What type of data is this? 25. It is also important to know what kind of plot is suitable for which data category; it helps in data analysis and visualization. Using a calculator, random numbers are generated and a student from a particular discipline is selected if he or she has a corresponding number. The term discrete means distinct or separate. A random number generator is used to pick two of those years. The sample probably consists more of people who prefer music because it is a concert event. It is classified into two broad categories: qualitative data and quantitative data. It can be the version of an android phone, the height of a person, the length of an object, etc. where n is the number of tips in the phylogeny ( ) , P is the continuous trait value of each species, and Q is the expected value of each species given the continuous trait model calculated following Equation (11) of Beaulieu et al. For example, you can not have a natural order for apple, orange, and banana. If she needed to, Lisa could have generated more random numbers. D. The Create a cluster sample by considering each state as a stratum (group). The numbers of programs installed on various computers ANSWERA.)

The data are discrete because the data can take on any value in an interval. State whether each situation is categorical or quantitative. Neither would be wrong, however. QUESTIONState whether the data described below are discrete or continuous, and explain why. It is not possible to measure qualitative data in terms of numbers and it is subdivided into nominal and ordinal data. Record the number. In this article, we have discussed the data types and their differences. Confounding: When the effects of multiple factors on a response cannot be separated. The numbers generated are as follows: 0.94360; 0.99832; 0.14669; 0.51470; 0.40581; 0.73381; 0.04399.

The data are continuous because the data can take b. state whether the data is continous or discrete The durations of a chemical reaction comma repeated several times Choose the correct answer below. You must choose 400 names for the sample. For example, if the population is 25 people, the sample is ten, and you are sampling with replacement for any particular sample, then the chance of picking the first person is ten out of 25, and the chance of picking a different second person is nine out of 25 (you replace the first person). according to measurement accuracy, it can be significantly subdivided into smaller sections. Data that can only take on certain values are discrete data. Ducks in a pond are discrete data because the number of ducks is a finite number. It is not possible to measure qualitative data in terms of numbers and it is subdivided into nominal and ordinal data. Two students carry three books, one student carries four books, one student carries two books, and one student carries one book. Besides herself, Lisas group will consist of Marcierz, Cuningham, and Cuarismo. O C. answer below. For example, suppose you have to do a phone survey. Number the population 120,000 and then use a simple random sample to pick a number that represents the first name in the sample. You sample five gyms. the chance of picking the first person for any particular sample is 1000 out of 10,000 (0.1000); the chance of picking a different second person is 999 out of 9,999 (0.0999); you do not replace the first person before picking the next person. A type of sampling that is non-random is convenience sampling. The action you just performed triggered the security solution. Sleep deprivation is of no use, instead, you should take a nap to relax the nerves of your brain in order to learn and study later. The results of convenience sampling may be very good in some cases and highly biased (favor certain outcomes) in others. Results are the outcome of our efforts and if you believe that you have put your best, then you will surely be able to score good marks. The freshman, sophomore, junior, and senior years are numbered one, two, three, and four, respectively. To four decimal places, 9/25 = 0.3600 and 9/24 = 0.3750. Press ENTER 15 times and record the numbers. To determine the proportion of people taking public transportation to work, survey 20 people in New York City. Discrete is data that can take only certain values. These data consist of audio, images, symbols, or text. Small letters like \(x\) or \(y\) generally are used to represent data values. B. feet, and 210 sq. For this example, suppose Lisa chooses to generate random numbers from a calculator. Lisa reads two-digit groups until she has chosen three class members (that is, she reads 0.94360 as the groups 94, 43, 36, 60). Instead of that, just revise what youve already done. We might make different choices of what we think is the best graph depending on the data and the context. State whether the data described below are discrete or continuous, and explain why. Qualitative or Categorical Data is data that cant be measured or counted in the form of numbers. OOO O A. The key difference between discrete and continuous data is that discrete data contains the integer or whole number. O C. When you analyze data, it is important to be aware of sampling errors and nonsampling errors. For example, call-in surveys are invariably biased, because people choose to respond or not. The amount a person grew (in height) in a year. Record the number of ones, twos, threes, fours, fives, and sixes you get in the following table (frequency is the number of times a particular face of the die occurs): Did the two experiments have the same results? LCM of 3 and 4, and How to Find Least Common Multiple, What is Simple Interest? Ordinal data have natural ordering where a number is present in some kind of order by their position on the scale. You can email the site owner to let them know you were blocked. You sample five students. Discrete. Required fields are marked *. Amount of money, pulse rate, weight, number of people living in your town, and number of students who take statistics are examples of quantitative data. The number of classes a student missed. the chance of picking the first person is 1,000 out of 10,000 (0.1000); the chance of picking a different second person for this sample is 999 out of 10,000 (0.0999); the chance of picking the same person again is 1 out of 10,000 (very low). Self-selected samples: Responses only by people who choose to respond, such as call-in surveys, are often unreliable. Height is continuous but we sometimes don't really worry too much about minor variations and club heights into a set of discrete data instead. Books for these classes tend to be expensive. These kinds of data can be considered in-between qualitative and quantitative data. Additional Resources Opinion poll posted online at: www.youpolls.com/details.aspx?id=12328 (accessed May 1, 2013). If we have quantitative data, such as the correct number of questions on a test, then the data can be continuous or discrete. The data he collects are summarized in the histogram. If you're asked whether age is a continuous or discrete variable in an Introductory Statistics class, the correct answer is technically continuous. O A. Making a schedule/timetable or studying together with your peers may help you in focusing and keep you active. Since this is the case, sampling without replacement is approximately the same as sampling with replacement because the chance of picking the same individual more than once with replacement is very low. If you and your friends carry backpacks with books in them to school, the numbers of books in the backpacks are discrete data and the weights of the backpacks are continuous data. Think about what contributes to making Doreens and Jungs samples different. Again, you sample the same five students. MAT 131 - Descriptive Statistics Ch. 1.2 - Types of Data - Quizlet Qualitative data tells about the perception of people. This particular bar graph in Figure \(\PageIndex{4}\) can be difficult to understand visually. A bar graph is appropriate to compare the relative size of the categories. O A. . Then survey every U.S. congressman in the cluster. For example, the number of subjects in a course, the number of families living in a block, the number of digits in a code, etc. This is completely natural. The exact lengths (in kilometers) of the ocean coastlines of different countries. No. Both samples are biased. For instance, hair color might be black, dark brown, light brown, blonde, gray, or red. If you feel tired at the moment, even that too is fine. The percent columns make comparing the same categories in the colleges easier. These kinds of data are also known as Numerical data. For example, the sample may not be large enough. A. Record the number and the first quiz score. Non-response or refusal of subject to participate: The collected responses may no longer be representative of the population. Larger samples are better, if possible.

Its really normal for you to feel anxious before your exam especially when the subject is statistics. A sample of 100 undergraduate San Jose State students is taken by organizing the students names by classification (freshman, sophomore, junior, or senior), and then selecting 25 students from each. B. A high school counselor uses a computer to generate 50 random numbers and then picks students whose names correspond to the numbers. Statistics and Probability questions and answers, CS State whether the data described below are discrete or continuous, and explain why. In polling, samples that are from 1,200 to 1,500 observations are considered large enough and good enough if the survey is random and is well done. The data are discrete because the data can only take on specific values. Sample size issues: Samples that are too small may be unreliable. Doreen and Jung each take samples of 500 students. There are distinct or different values in discrete data. Students often ask if it is "good enough" to take a sample, instead of surveying the entire population. Just as there is variation in data, there is variation in samples. Each random number may only contribute one class member. It was mentioned previously that two or more samples from the same population, taken randomly, and having close to the same characteristics of the population will likely be different from each other. Samples that contain different individuals result in different data. Click to reveal Determine whether the given value is from a discrete or continuous data State whether the data described below are discrete or continuous, and explain why The speeds of the different people walking in a park Choose the correct answer below. Compare the fractions 9/25 and 9/24. Collecting data carelessly can have devastating results. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. 1. Whether you are a data scientist, marketer, businessman, data analyst, researcher, or you are in any other profession, you need to play or experiment with raw or structured data. It would be great if you already have a bit of knowledge about a course before opting for it. For example, in the case of statistics, algebra is a good option to learn before starting your statistics course. c. Two graphs that are used to display qualitative data are pie charts and bar graphs. Data may come from a population or from a sample. The other examples of qualitative data are : Difference between Nominal and Ordinal Data, Difference between Discrete and Continuous Data, 22 Top Data Science Books Learn Data Science Like an Expert, PGP In Data Science and Business Analytics, PGP In Artificial Intelligence And Machine Learning, Nominal data cant be quantified, neither they have any intrinsic ordering, Ordinal data gives some kind of sequential order by their position on the scale, Nominal data is qualitative data or categorical data, Ordinal data is said to be in-between qualitative data and quantitative data, They dont provide any quantitative value, neither can we perform any arithmetical operation, They provide sequence and can assign numbers to ordinal data but cannot perform the arithmetical operation, Nominal data cannot be used to compare with one another, Ordinal data can help to compare one item with another by ranking or ordering, Discrete data are countable and finite; they are whole numbers or integers, Continuous data are measurable; they are in the form of fractions or decimal, Discrete data are represented mainly by bar graphs, Continuous data are represented in the form of a histogram, The values cannot be divided into subdivisions into smaller pieces, The values can be divided into subdivisions into smaller pieces, Discrete data have spaces between the values, Continuous data are in the form of a continuous sequence, Opinion on something (agree, disagree, or neutral), Colour of hair (Blonde, red, Brown, Black, etc. If these data-driven topics got you interested in pursuing professional courses or a career in the field of Data Science.

That is, a member of the population may be chosen only once. If you sample without replacement, then the chance of picking the first person is ten out of 25, and then the chance of picking the second person (who is different) is nine out of 24 (you do not replace the first person). You can also visit their website. Working on data is crucial because we need to figure out what kind of data it is and how to use it to get valuable output out of it. The number of books in a rack is a finite countable number. It is easy in many cases, discrete data is preceded by the number of, which makes the differentiation of results easier. Gathering information about an entire population often costs too much or is virtually impossible. This variability in samples cannot be stressed enough. Instead, we use a sample of the population. Step 2: Discrete and continuous data. Record the quiz scores that correspond to these numbers. These data are represented mainly by a bar graph, number line, or frequency table. Data may be classified as qualitative, quantitative continuous, or quantitative discrete. There are particular calculators for different statistics exams and having good knowledge about their use and implementation would be great. feet, 180 sq. If quantitative, state whether it's discrete or continuous. Read the study carefully to evaluate the work. Roll one fair die (six-sided) 20 times. Problems with samples: A sample must be representative of the population. The station wants to know if its audience would prefer more music or more talk shows. The data are because.continuous the data can take on any value in an interval B. You can get study material, solved and unsolved questions, and also quizzes which will help you test your knowledge. Nominal Data is used to label variables without any order or quantitative value. A high school educational researcher interviews 50 high school female teachers and 50 high school male teachers.

To determine the average cost of a two-day stay in a hospital in Massachusetts, survey 100 hospitals across the state using simple random sampling. Convenience sampling involves using results that are readily available. Instructions: Use the Random Number Generator to pick samples. A.The data are continuous because the data can only take on the data can only take on specificvalues. For example, it does not make sense to find an average hair color or blood type. Solved State whether the data described below are discrete - Chegg Excelling your basic knowledge about the subject promotes conceptual learning and hence, you can easily get familiar with new concepts too. A large ship is sailing between three small islands. Your email address will not be published. The colors red, black, black, green, and gray are qualitative data. The job of the statistician is to see through the variability and draw appropriate conclusions. We may prefer not to think of 10,00,100 and 10,00,102 as crucially different values, but instead as nearby points on an approximate continuum. A random number generator is used to select a student from the alphabetical listing of all undergraduate students in the Fall semester. Show how you know.

The color of hair can be considered nominal data, as one color cant be compared with another color. Different types of data are used in research, analysis, statistical analysis, data visualization, and data science. Misleading use of data: improperly displayed graphs, incomplete data, or lack of context. When properly selected, larger samples model the population more closely than smaller samples. Data that can take a decimal value and can vary across a range is called . You can specify conditions of storing and accessing cookies in your browser. For any particular sample of 1,000, if you are sampling with replacement. To choose a stratified sample, divide the population into groups called strata and then take a proportionate number from each stratum. b. Q: Classify the Following as Discrete and Continuous Data. answer below. The data are the areas of lawns in square feet. In the graph, the percentages add to more than 100% because students can be in more than one category. Probably not. Any group of n individuals is equally likely to be chosen by any other group of n individuals if the simple random sampling technique is used. To choose a systematic sample, randomly select a starting point and take every nth piece of data from a listing of the population. feet, 160 sq. The data are continuous because the data can only take on specific values. Do not automatically assume that the study is good, but do not automatically assume the study is bad either. Continuous data is the data that can be of any value. As a rule, the larger the sample, the smaller the sampling error. To choose a simple random sample of size three from the other members of her class, Lisa could put all 31 names in a hat, shake the hat, close her eyes, and pick out three names. .
