Hi
A. Nice dataset for demonstrating contingency chi2 and goodness of fit chi2.
Here's the analyses in SPSS.
data list free / gend assign freq.
begin data
1 1 8
1 2 6
2 1 2
2 2 33
end data.
weight by freq.
crosstabs /tables = gend by assign /stat = all.

B. Two interesting questions implied by Ken's data, given significant effects
shown above.
B1. Why aren't males more motivated to complete such assignments?
B2. Why aren't psychology courses being chosen more equally by male and female
students?
Take care

I just finished grading an easy *extra-credit* assignment.
Completion of the assignment (a 1-page analysis of an
advertisement) resulted in 0.5 point on the final grade.
Here are the results:
Turn in Assignment Male Female
Yes 6 33
No 8 2
