Question

Identify whether each statement is true or false.

1.In experimental design, classification variables are independent variables.

2.The statistical methods of analysis of variance assume that the populations are normally distributed.

3.Determining the table value for the F distribution requires two values for degrees of freedom.

4.The F value for treatment will always increase if we include a blocking effect.

5.The Tukey-Kramer procedure is based on construction of confidence intervals for each pair of treatment means at a time.

6.In analysis of variance tests a F distribution forms the basis for making the decisions.

7.The statistical methods of analysis of variance assume equal sample means.

8.In experimental design, a variable that the experimenter controls or modifies in the experiment is called a treatment variable.

9.Analysis of variance may be used to test the differences in the means of more than two independent populations.

10.Homogeneity of variance test gives inference whether the group means are equal.
