Question

The use of inferential statistics permits the research to:

A. Generalize to a population based on information gathered from a sample
B. Describe information obtained from empirical observation
C. Interpret descriptive statistics
D. Reject the null hypothesis

Answer 1

Inferential statistics are used to make generalizations about a population based on sample data, to construct confidence intervals, and to perform hypothesis testing such as t-tests.

Step-by-step explanation:

The use of inferential statistics enables researchers to generalize to a population based on information gathered from a sample. By analyzing sample data, statisticians can estimate population parameters, construct confidence intervals, and perform hypothesis testing. For instance, when employing a t-test, a statistician might compare the mean values between two groups to determine if there is a significant difference, ultimately helping to reject the null hypothesis if sufficient evidence exists.
