The test statistic of the completely randomized ANOVA design equals:

A) sum of squares for treatments / sum of squares for error
B) sum of squares for error / sum of squares for treatments
C) mean square for treatments / mean square for error
D) mean square for error / mean square for treatments
E) sum of squares for error / mean square for error

Completely Randomized Design

A type of experimental design where all subjects are randomly assigned to treatments without any restrictions or stratifications.

Test Statistic

A value calculated from sample data during a hypothesis test, used to determine whether to reject the null hypothesis.

Mean Square

A method used in statistical analysis that takes the sum of squares of variables divided by their degrees of freedom, often used in the context of ANOVA.
