Question

which of the following is not a requirement for using one - way analysis of variance for testing equality of three or more population means?
choose the correct answer below.
a. the samples are simple random samples of quantitative data.
b. the samples are matched or paired in some way.
c. the populations have distributions that are approximately normal.
d. the different samples are from populations that are categorized in only one way.

Explanation:

One-way ANOVA requires independent simple random samples of quantitative data, approximately normal population distributions, and categorization of populations by one factor. Matched/paired samples are for dependent tests (e.g., paired t-test), not one-way ANOVA.

Answer:

B. The samples are matched or paired in some way.
