This page will perform a two-way factorial analysis of variance for designs in which there are 2-4 randomized blocks of matched subjects, with 2-4 repeated measures for each subject. The programming assumes that each row includes a separate set of matched subjects and that the repeated measures occur within the rows and across the columns. The one-way, or one-factor, ANOVA test for independent measures is designed to compare the means of three or more independent samples (treatments) simultaneously. To use this calculator, simply enter the values for up to five treatment conditions (or populations) into the text boxes below, either one score per line or as a comma delimited list. Stats: Two-Way ANOVA. The two-way analysis of variance is an extension to the one-way analysis of variance. There are two independent variables (hence the name two-way). Assumptions. The populations from which the samples were obtained must be normally or approximately normally distributed. Understanding Two Way ANOVA Minitab output. The results of running a 2*3 ANOVA on Minitab are presented below. DF is degrees of freedom, Coupon Level has 1 DF(2 levels – 1=1) and In Store Promotion has 2 DF(3 levels-1=2). SS is the Sum of Squares or also known as SS(between). This is the variation in Y related to the variation in the means of the categories of X. this represents variation between the categories of X or the portion of the sum of squares in Y related to X.

## A good online presentation on ANOVA in R can be found in ANOVA section of in the base stats package produces plots for two-way interactions. plotmeans( )

The one-way, or one-factor, ANOVA test for independent measures is designed to compare the means of three or more independent samples (treatments) simultaneously.

A two-way ANOVA is an extension of the one-way ANOVA. With a one-way, you have one independent variable affecting a dependent variable. With a two-way ANOVA, there are two independents. For
