Consider a Two-Way Analysis of Variance Experiment with Treatment Factors

question 52

Short Answer

Consider a two-way analysis of variance experiment with treatment factors A and B, with factor A having four levels and factor B having three levels. The results are summarized below.
Compute the mean squares and appropriate F statistics to test the null hypotheses of no effect from either factor at α = .05 (assumption: no interaction effect).

Definitions:

Pooled Variance

A weighted average of variances from multiple samples, often used in statistical procedures to estimate a common variance.

Test Statistic

A value calculated from sample data during a hypothesis test that is used to determine whether to reject the null hypothesis.

Sample Size

The number of individuals or observations included in a sample, which represents part of a larger population for the purpose of conducting statistical analysis.

ΣD

Symbolizes the sum of differences, often used in statistical formulas to denote the aggregate of specific differences.
