It is not possible to measure qualitative data in terms of numbers and it is subdivided into nominal and ordinal data. Quantitative data, on the other hand, is one that contains numerical values and uses a scope. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. The three cans of soup, two packages of nuts, four kinds of vegetables and two desserts are quantitative discrete data because you count them. That is, a member of the population may be chosen only once. The following pie charts have the Other/Unknown category included (since the percentages must add to 100%). A.

You can specify conditions of storing and accessing cookies in your browser. The data are continuous because the data can only take on specific values. Data is classified into 4 types. However for practical reasons, in most populations, simple random sampling is done without replacement. Discrete data: When numerical data has values that are countable and specific to a particular category, it is called discrete data. It would be great if you already have a bit of knowledge about a course before opting for it. The data are continuous because the data can only take on specific values. Here are a few steps to prepare well for your exam which has statistics as a part of the course. A random number generator is used to select a student from the alphabetical listing of all undergraduate students in the Fall semester. Otherwise, the variable is nominal. Thats why it is also known as Categorical Data. A defective counting device can cause a nonsampling error. If all the money in the 555, find the number of 10 coins in it 12. You cannot expect your brain to work nicely with hundreds of thoughts, it will only create a mess. A pie chart cannot be used. Over time, some continuous data can change. 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. You should ask the doubt there and then clear it, analyze it and work on it. 25. Still, continuous data stores the fractional numbers to record different types of data such as temperature, height, width, time, speed, etc. Systematic sampling is frequently chosen because it is a simple method. If you feel like your doubt is stupid and you skip it rather than ask it, it is not the correct approach. 1.2.13 State whether the data described below are discrete or continuous and explain why.The times required by students to complete a statistics test Choose the correct answer below.

State whether the data described below are discrete or continuous, and explain why. The term discrete means distinct or separate. A. Random sampling methods include simple random sampling, stratified sampling, cluster sampling, and systematic sampling. Therefore this is discrete data. 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). The durations of a chemical reaction comma repeated . For these samples, each member of the population did not have an equally likely chance of being chosen. Compare the fractions 9/25 and 9/24. The data are continuous because the data can only take on specific values. The data are continuous because Also, the sample represents only those who showed up to the event earlier than the majority. We choose ten different part-time students from the disciplines of chemistry, math, English, psychology, sociology, history, nursing, physical education, art, and early childhood development. 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. Continuous data. A discrete variable, on the other hand, can only take on specific values.
