One-way ANOVA is used to measure information from:
ASeveral groups
BOne single value
CTwo paired points
DNo groups at all
Answer & Solution
Correct answer: A. Several groups
1. ANOVA compares more than two samples at once.
2. One-way ANOVA is used to measure information from several groups.
3. It rests on the F distribution.
4. A two-sample test would not handle several groups together.
