The data are discrete because the data can only take on specific values. It is not possible to measure qualitative data in terms of numbers and it is subdivided into nominal and ordinal data. What type of data is this? To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. 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). B. Data are individual items of information that come from a population or sample. Divide into groups of two, three, or four. Asking all 10,000 students is an almost impossible task.

Statistical data needs to be critically analyzed, not simply accepted. the distance it is from your home to the nearest grocery store. B. c. The data are continuous because the data can take on any value in an interval. However the third random number, 0.14669, contains 14 (the fourth random number also contains 14), the fifth random number contains 05, and the seventh random number contains 04. Measurements of the amount of beverage in a 16-ounce can may vary because different people make the measurements or because the exact amount, 16 ounces of liquid, was not put into the cans. Still, continuous data stores the fractional numbers to record different types of data such as temperature, height, width, time, speed, etc. Over time, some continuous data can change. Discrete Data Examples: The number of students in a class, the number of chocolates in a bag, the number of strings on the guitar, the number of fishes in the aquarium, etc. Suppose Doreen and Jung both decide to study the average amount of time students at their college sleep each night. This is true even when the samples are well-chosen and representative of the population. Examples of discrete variables are the number of students and age. 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 first sample probably consists of science-oriented students. Tables are a good way of organizing and displaying data. Factors not related to the sampling process cause nonsampling errors. Step 2: Discrete and continuous data.
State whether the data described below are discrete or - JustAnswer LBCC Distance Learning (DL) program data in 2010-2011. lastbaldeagle. A. In reality, a sample will never be exactly representative of the population so there will always be some sampling error. O C. For this example, suppose Lisa chooses to generate random numbers from a calculator.
Discrete and Continuous Data - Definitions, Examples - VEDANTU All data that are the result of measuring are quantitative continuous data assuming that we can measure accurately. The data are continuous because the data can take The data are discrete because the data can only take on specific values. air. 13. An administrative assistant is asked to stand in front of the library one Wednesday and to ask the first 100 undergraduate students he encounters what they paid for tuition the Fall semester. There are a number of options if you go for the statistics degree. You measure continuous data. These data consist of audio, images, symbols, or text. discrete because the data can only take on specific values . Also, in both cases, not all students have a chance to be in either sample. The station uses convenience sampling and surveys the first 200 people they meet at one of the stations music concert events. Learn data analytics or software development & get guaranteed* placement opportunities. For the purpose of analysis, data are presented as the facts and figures collected together. Pick three quiz scores randomly from each column. A. A completely random method is used to select 75 students. As a rule, the larger the sample, the smaller the sampling error. A continuous data set because there are infinitely many possible values and those values cannot be counted. Sample size issues: Samples that are too small may be unreliable. Compare the fractions 9/25 and 9/24. This website is using a security service to protect itself from online attacks. A high school principal polls 50 freshmen, 50 sophomores, 50 juniors, and 50 seniors regarding policy changes for after school activities.

You sample five students. Statistics is a quite tough subject but for those who know how to use their mind, its the best one for them as it involves more practical knowledge and conceptual learning. Experts are tested by Chegg as specialists in their subject area. Gathering information about an entire population often costs too much or is virtually impossible. Number each department, and then choose four different numbers using simple random sampling. It is easy in many cases, discrete data is preceded by the number of, which makes the differentiation of results easier. They may be related (correlated) because of their relationship through a different variable. These data dont have any meaningful order; their values are distributed into distinct categories. A.The data are continuous because the data can only take on the data can only take on specificvalues. Manufacturers regularly run tests to determine if the amount of beverage in a 16-ounce can falls within the desired range. Also read: 22 Top Data Science Books Learn Data Science Like an Expert.

This site is using cookies under cookie policy . Hint: Data that are discrete often start with the words "the number of." the number of pairs of shoes you own. It includes only those values which are separate and can only be counted in whole numbers or integers, which means that the data can not be split into fractions or decimals. Evaluate it on its merits and the work done. Data may be classified as qualitative, quantitative continuous, or quantitative discrete. Statistics and Probability questions and answers, CS State whether the data described below are discrete or continuous, and explain why. Opinion poll posted online at: www.youpolls.com/details.aspx?id=12328 (accessed May 1, 2013). The data are continuous because the data can take the type of car you drive.

It is classified into two broad categories: qualitative data and quantitative data. The data are continuous because the data can only take on specific values. 8. Try this experiment twice. The road from A to E and the road from C and D are perpendicular and intersect at point F. Theresa's house is at C, 500 feet from the intersection. It may take any numeric value, within a potential value range of finite or infinite. State whether the data described below are discrete or continuous, and explain why: . Then use simple random sampling to choose proportionate numbers from the first department and do the same for each of the remaining departments. Problems with samples: A sample must be representative of the population. Experts are tested by Chegg as specialists in their subject area. The distance from G to H in State whether the data described below are discrete or continuous, and explain why. 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. b. Tips and Tricks to study Discrete and Continuous Data, Age is discrete data because we could be infinitely precise and use an infinite number of decimal places, rendering age continuous as a result. Quantitative data can be used for statistical manipulation. The table displays Ethnicity of Students but is missing the "Other/Unknown" category. Press MATH. Each method has pros and cons.
Determine whether the value is from a discrete or continuous data set If we have quantitative data, such as the correct number of questions on a test, then the data can be continuous or discrete. Different types of data are used in research, analysis, statistical analysis, data visualization, and data science. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. The data are discrete because the data can take on any value in an interval. Another example is learning how to use calculators. 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.
