QM2 W5

One-way ANOVA is used to compare the means of three or more independent groups based on one independent variable.

• True

• False

Two-way ANOVA allows researchers to examine the effect of two independent variables simultaneously on a dependent variable.

• True

• False

In both one-way and two-way ANOVA, increasing the number of groups will decrease the degrees of freedom for the error term.

• True

• False

Standard error can increase with the number of groups in a one-way ANOVA if the group variances are unequal.

• True

• False

A significant interaction effect in a two-way ANOVA indicates that the effect of one independent variable is the same at all levels of the other independent variable.

• True

• False

Both one-way and two-way ANOVA assume that the samples are drawn from populations with equal variances (homogeneity of variance).

• True

• False
