Question 2:

Description: Researchers were interested in whether the location of the primary body of water in which Florida alligators spend most of their time is associated with the alligators’ weight in pounds. Here are summary statistics for the 3 locations:

The researchers fit a one way ANOVA model utilizing the following SAS code:

proc glm data=alligator;

class location;

            model Weight_pounds=location;

estimate 'contrast ' location 0.5 -1 0.5;

run;

quit;

Here is partial output from this ANOVA model.

Question 2: How many numerator degrees of freedom and denominator degrees of freedom are associated with your F-statistic?

a. Numerator df =

b. Denominator df=

Explanation / Answer

For numerator and denominator df, we need to check the model and error values in the df column of ANOVA table respectively.

Hence,

Numerator df = 2

Denominator df = 22
