## SPSS Help Tells About Analysis Of Variance

Analysis of variance is a very powerful tool that can help researchers, businessmen, marketing specialists and students to test their hypotheses and come to certain conclusions. So, why did they call it variance analysis? At first it might sound odd, but analysis of variance is derived from the fact that one needs to compare variances in order to test for statistical significance between means. There are many types of variance analyses like ANOVA, MANOVA, ANCOVA, t-test, General Linear Model, Repeated Measure Design, contrast effects, assumptions, post-hoc comparisons, etc.

## SPSS Help Tells About The Purpose of Variance Analysis

So, what is the purpose for analyzing variance? – It allows researchers to test for significant differences between means. If researchers are comparing two means, then simple t-test can be used, but if there are more than two means, ANOVA will produce more reliable results. ANCOVA is one other test which analyzes covariance, which can also be very helpful to students and researchers; however, these and other types of variance analysis tests are quite challenging to perform if you don’t know theory behind them and general statistical knowledge.
