25 pea pods were broken apart and the number of peas in each pod recorded. The record looked as follows:

# peas in pod; 2,3,4,5,6 and frequency; 7,9,5,3,1

Make a histogram for this data, does this data appear to be skewed?

What is the model class for this survey?

It is skewed, if it seems to have a tail (or much longer tail) at one end.

I'm not sure what you mean by "model class."
