What does ANOVA stand for?
Analysis of variance
When is it appropriate to use an ANOVA?
When a dataset is made up of three or more groups.
Which of the following is a TRUE statement regarding an ANOVA?
The F ratio compares the variance within samples to the variance between samples.
3 multiple choice options
The ____________ determines the type of ANOVA to run on a dataset.
number of factors (independent variables)
Which of the following items are needed in order to locate the critical value for an
ANOVA using the table? Select all that apply.

True or False: An economist wants to compare the mean annual income of
employees at four Fortune 500 companies. Analysis of variance cannot be used
because there are more than three populations.
False
An ANOVA can be used for research designs with three or more groups.
Samples of theme park wait times are obtained and compared. Five major theme
parks are compared, and their mean wait times are recorded. Identify the null
hypothesis and alternative hypotheses for applying an analysis of variance.
Ho: All five theme parks have the same mean wait times.
Ha: At least one of the five theme parks has a mean wait time that is different from
the others.
What does an F-value below 1 indicate? What does an F-value above 1 mean?
Answer: A small F (F < 1) indicates that the variation within the groups is greater
than the variation between group means. In contrast, a large F (F > 1) indicates that
the variation between the group means is greater than the variation within the
groups. The greater the value of F, the more likely it is that a true difference exists
between the group means.
