Solution Preview

In order to use an ANOVA we must assume that each of the samples is drawn from a normal population and that each of these populations has the same variance. However if the sample sizes are large enough that is more than 30 , we do not need the assumption of normality.

A One-Way Analysis of Variance is a way to test the equality of three or more means at one time by using variances.
Assumptions:

* The populations from which the samples were obtained must be normally or approximately normally distributed.
* The samples must be independent.
* The ...

  • ANOVA versus a t-test

    The t-tests can only be done between two data sets, or between one set and a "true" value - An ANOVA uses the F distribution instead of the t-distribution - An ANOVA assumes that all of the data sets have equal variances - Use caution on close decisions

  • Post Hoc Tests

    One of the advantages of using an ANOVA (compared to using t-tests) is also a disadvantage—using an ANOVA makes it necessary to use post hoc tests if there is a significant main effect.

  • background for ANOVAs and t-tests

    ANOVA vs t-test An ANOVA is closely related to a t-test in that a t-test looks at the difference between the means of two groups (two samples) while an ANOVA looks at the difference of means between three or more groups.
