Textbook Problem

A researcher conducts an independent-measures, two-factor study using a separate sample of *n* = 15 participants in each treatment condition. The results are evaluated using an ANOVA and the researcher reports an *F*-ratio with *df* = 1, 84 for factor *A,* and an *F*-ratio with *df =* 2, 84 for factor *B.*

**a.** How many levels of factor *A* were used in the study?

**b.** How many levels of factor *B* were used in the study?

**c.** What are the *df* values for the *F*-ratio evaluating the interaction?

**a.**

To determine

**To Find:** The number of Levels for factor A were used in study.
