ANOVA

What is the alternative hypothesis in ANOVA?

• The proportion of the total variation in the dependent variable explained by the variation in the independent variable

• The measure of the dispersion of the data around the mean

• There is no significant difference between the groups; any observed difference may be due to chance and sampling error

• There is a significant difference between the groups; the observed differences are likely not due to chance or sampling error

The ANOVA test is a statistical test that can be done in place of multiple T-tests

• True

• False

In IB ESS, if given a choice, you will want to select "____ way ANOVA"
