Question 16 / 30
In the picture, how many runs are in the red box? How many deviations from this treatment mean? How many degrees of freedom for error under this treatment?

In the picture, how many runs are in the red box? How many deviations from this treatment mean? How many degrees of freedom for error under this treatment?

hard
 
Question 17 / 30

In the picture on the left, we see 3 runs under level 1 of the factor. This means there is a mean and consequently 2 degrees of freedom for error with respect to this mean. We have 4 all together.

hard
 
Question 18 / 30
In the picture we see 6 data points, and 1 grand mean. This means we can calculate 5 deviations from this mean the 6 is forced by the values of the first 5. So we have only 5 degrees of freedom.

hard
 
Question 20 / 30
In the table below, if I increase n, what happens to the number of dots in a scatter diagram at every treatment level? Do the dots increase in number vertically or horizontally?

In the table below, if I increase n, what happens to the number of dots in a scatter diagram at every treatment level? Do the dots increase in number vertically or horizontally?

expert
 
Question 21 / 30
If I increase a in the table below, what will happen to the number of dots in a scatter diagram? Will the increase come from adding dots vertically at every level or horizontally WITH new levels?
