The _____ is another term for the variance of the sample data.

When the F- test statistic is greater than the critical F- score for ANOVA, the correct conclusion is to fail to reject the null hypothesis.

If the null hypothesis is true for one- way ANOVA, we would expect MSB to be larger than MSW, causing the critical F- score to exceed 1.0.

There is no interaction between Factors A and B when the data values for each level of one factor behave in the same fashion across all levels of the other factor.

If the null hypothesis is true, the mean square total is a good estimate for the population variance.

The Tukey- Kramer multiple comparisons procedure allows us to examine each pair of sample means and to conclude whether or not their respective sample means differ for a one- way ANOVA.

If the main factor for randomized block ANOVA is statistically significant, you should _______.

Suppose a one- way ANOVA procedure is being used to compare the means of five different populations. The number of sample means to examine using the Tukey- Kramer multiple comparisons test is ____

In a two- way ANOVA procedure, the results of the hypothesis test for Factor A and Factor B are only reliable when the hypothesis test for the interaction of Factors A and B is statistically insignificant.

The critical value for the Tukey- Kramer critical range is found using the F- distribution.

With randomized block ANOVA, the size of each sample needs to be the same.

The mean square within (MSW)provides a good estimate of the population variance only if the null hypothesis is true.

For randomized block ANOVA, we partition the total sum of squares (SST)into the sum of squares between (SSB)and the sum of squares block (SSBL).

If the null hypothesis is true for one- way ANOVA, the mean square total (MST)would be a good estimate for the ______.

In a two- way ANOVA procedure, there are two hypotheses to be tested-the test for Factor A and the test for factor B.

The appropriate test statistic for the blocking factor for a randomized block ANOVA follows the F- distribution.

Two- way ANOVA incorporates a blocking factor to account for variation outside of the main factor in the hopes of increasing the likelihood of detecting a variation due to the main factor.

A factor in an ANOVA test describes the cause of the variation in the data.

For two- way ANOVA, we partition the total sum of squares (SST)into the sum of squares for Factor A (SSFA), the sum of squares for Factor B (SSFB), the sum of squares interaction (SSAB), and the sum of squares error (SSE).

A ______ represents the number of data values assigned to each cell in a two- way ANOVA table.
