Each student is chosen using simple random sampling. Nominal Data is used to label variables without any order or quantitative value. Data that can only take on certain values are discrete data. A high school counselor uses a computer to generate 50 random numbers and then picks students whose names correspond to the numbers. A large ship is sailing between three small islands. You must choose 400 names for the sample. The data are continuous because What type of data is this? Be aware that many large samples are biased.

These kinds of data are also known as Numerical data. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. This website is using a security service to protect itself from online attacks. Discrete data is a sort of numerical data that consists of full, concrete numbers that have particular and fixed data values that are determined by counting. The data are discrete because the data can only take on specific values. Statistics and Probability questions and answers, state whether the data is continous or discrete The durations of Qualitative or Categorical Data is data that cant be measured or counted in the form of numbers. The durations of a chemical reaction comma repeated . Also, the sample represents only those who showed up to the event earlier than the majority. State whether the data described below are discrete or continuous, and explain why. If she needed to, Lisa could have generated more random numbers. 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. According to a report, today, at least2.5 quintillion bytes of data are produced per day.

In today's changing times, pursuing a career in this subject is known to provide some of the most sought professional options. These values do not have to be complete numbers, but they are values that are fixed. 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. Question: CS State whether the data described below are discrete or continuous, and explain why. Save my name, email, and website in this browser for the next time I comment.

This is completely natural. That is, once a member is picked, that member goes back into the population and thus may be chosen more than once. Data may be classified as qualitative, quantitative continuous, or quantitative discrete. We all know that time is very important, it doesnt wait for anyone. It is better for the person conducting the survey to select the sample respondents. Press 5:randInt( and enter 1,6). Over time, some continuous data can change. A type of sampling that is non-random is convenience sampling. Statistical data about spreading of the epidemic are known in discrete periods of time, for example twenty-four hours. Most samples are taken from large populations and the sample tends to be small in comparison to the population. according to measurement accuracy, it can be significantly subdivided into smaller sections.

Hint: Data that are discrete often start with the words "the number of." the number of pairs of shoes you own. continuous, and explain why. Press 5:randInt( and enter 1, 60). Data is classified into 4 types. Neither would be wrong, however. 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). Each undergraduate student in the fall semester has the same probability of being chosen at any stage of the sampling process. If you feel like your doubt is stupid and you skip it rather than ask it, it is not the correct approach. The circumferences (in inches) of people's heads Choose the correct answer below.
