1 ANOVA ANOVA is used when more than two groups are compared In order to conduct an ANOVA, several assumptions must be made – The population from which the samples are drawn are normally distributed – The populations from which the samples are drawn have equal variances

2 Partitioning Variances When conducting an ANOVA, the variances of the groups are partitioned into between- group variance and within-group variance

3 Mean Squares

4 Decision Making for ANOVA The F-Distribution is used to obtain the critical value for an ANOVA

Lesson #23 Analysis of Variance. In Analysis of Variance (ANOVA), we have: H 0 :  1 =  2 =  3 = … =  k H 1 : at least one  i does not equal the others.
