Math Problem Statement

The ________________ is an example of a descriptive statistic. Group of answer choices

ANOVA

t-test

standard deviation

chi-square

Kruskal Wallis

Solution

The correct answer is standard deviation.

Explanation:

  • Descriptive statistics summarize and describe the main features of a data set, often through measures like mean, median, mode, variance, and standard deviation.
  • ANOVA, t-test, chi-square, and Kruskal Wallis are examples of inferential statistics, which are used to make inferences or test hypotheses about a population based on sample data.
