Descriptive and Inferential Statistics

Descriptive Statistics

Answers

  1. The two divisions of statistics are inferential and descriptive. (See the text for more details.)

  2. Descriptive statistics summarize and describe data. Inferential statistics use data from a sample to answer questions about a population. Inferential statistics involves generalizing beyond the data at hand.

  3. Descriptive statistics are numbers that are used to summarize and describe data. Predicting next month's unemployment rate involves predicting future data, no describing the data at hand.
