What are some business situation in which ANOVA would be more appropriate than a (Z) or (t) test?


Solution Description

The advantage that ANOVA has over both the (Z) and (t) test is that multiple variables can be tested at the same time instead of running two different experiments. A t-test only compares one variable with two groups and the Z-test compares the sample and population means to determine a significant difference.  With ANOVA, three or more means can be compared without increasing the chance of committing a type I error, which is rejecting a null hypothesis when it is true.
