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.
