2 A balanced design will be an orthogonal design

True

False

3
An orthogonal design will necessarily be balanced

True

False

4.

A regression line with a categorical factor added in as well will essentially create separate trendiness for each of the levels of the categorical factor.

True

False

5 If there is an interaction between a categorical factor and a quantitative variable in a regression, it will allow the slopes to differ across the groups.

True

False

6
A quadratic model for a quantitative explanatory variable can be viewed as a self-interaction

True

False

7
If you have a categorical factor in a model where that factor does have an effect on the response variable, the F-ratio will tend to grow larger as the number of datapoints per level increases.

True

False

8
If you have a categorical factor in a model where that factor does have an effect on the response variable, the MSE tends to grow smaller as the number of datapoints per level increases.

True

False

9
If you have a categorical factor in a model where that factor does have an effect on the response variable, the MS for the model tends to grow as the number of datapoint per level increases.
