Introduction to Analysis of Variance
Analysis of Variance Defined (Continued)
- ANOVA is a preparatory procedure to indicate the advisability of making the specific t tests to test the statistical significance between specific pairs of means.
- As the name implies, this procedure is used to break down or analyze the total variance of a matrix into its separate and independent variances attributable to the various experimental factors.
- A ratio is then made of the two independent variance estimates.
- This ratio is then compared with the critical F-ratio found in your F table.
