Questions: Explain the difference between descriptive and inferential statistics. Choices the correct answer below. B. Descriptive statistics offers conclusions about the sets of data based on sampling. Inferential statistics summarizes the information revealed in data sets. C. Descriptive statistics is a characteristic or property of an individual experimental unit. Inferential statistics is the process used to assign numbers to variables of individual population units. D. Descriptive statistics describes sets of data. Inferential statistics draws conclusions about the sets of data based on sampling.

The answer is D: Descriptive statistics describes sets of data. Inferential statistics draws conclusions about the sets of data based on sampling.

Explanation:

A. This option is incorrect because it reverses the roles of descriptive and inferential statistics. Descriptive statistics do not involve drawing conclusions based on sampling; rather, they summarize and describe the features of a data set.

B. This option is incorrect because it also reverses the roles. Descriptive statistics summarize the information revealed in data sets, while inferential statistics involve making conclusions about a population based on a sample.

C. This option is incorrect because it mischaracterizes both types of statistics. Descriptive statistics are not about characteristics or properties of individual experimental units, and inferential statistics are not about assigning numbers to variables.

D. This option is correct because it accurately describes the roles of both types of statistics. Descriptive statistics involve summarizing and describing the main features of a data set, such as through measures of central tendency and variability. Inferential statistics involve using data from a sample to make inferences or predictions about a larger population.
