Answer

The study of statistics has two major branches: descriptive statistics and inferential statistics.

Work Step by Step

Descriptive statistics is the branch of statistics that involves the organization, summarization, and display of data. For example, descriptive statistics involves statements such as “For unmarried men, approximately 70% were alive at age 65” and “For married men, 90% were alive at 65.” Inferential statistics is the branch of statistics that involves using a sample to draw conclusions about a population. A basic tool in the study of inferential statistics is probability. For example, inferential statistics involves statements such as "being married is associated with a longer life for men".
