Four young children were monitored closely over a perios of several weeks to measure how much they watched violetn televisions programs and thier amount of violent behavior toward their plamets. The results were as follows.
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 .05 signigicance level, two tailed);
e) explain the logic of what you have done, writing as if you were 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 causalty, indicating for each direction whether it is a reasonable explanation for the correlation in light of the variables involved. (and why)
Thank you
