a) Make a scatter diagram of the

scores; (b) describe in words the general pattern of correlation, if any; (c) figure

the correlation coefficient; (d) figure whether the correlation is statistically significant

(use the .05 significance level, two tailed); (e) explain the logic of what

you have done, writing as if you are speaking to someone who has never heard

of correlation (but who does understand the mean, deviation scores, and hypothesis

testing); and (f) give three logically possible directions of causality, indicating

for each direction whether it is a reasonable explanation for the correlation

in light of the variables involved (and why).
