anova-two-way-variables-unequal-cell-sizes (iv1 iv2 dv)

Calculates the analysis of variance when there are two factors that may

affect the dependent variable, specifically ` iv1' and `

iv2.'

Unlike the one-way ANOVA, there are mathematical difficulties with the two-way

ANOVA if there are unequal cell sizes. This function differs fron the standard

two-anova by (1) the use of cell means as single scores, (2) the division of

squared quantities by the number of cell means contributing to the quantity

that is squared and (3) the multiplication of a “sum of squares” by the harmonic

mean of the sample sizes.

The result of the analysis is an anova-table, as described in the manual.

See the manual for further discussion of analysis of

variance. The row effect is ` iv1' and the<br> column effect is `

iv2.'
