At a recent halloween party, the women appeared to be consuming more packages of halloween candy than were the men. If the mean number of packages consumed by the 3 men was 4, and that for the 7 women was 6, and the standard deviation for the whole group was 2 packages, what was the correlation between gender and the number of packages consumed?
I had used the the point-biserial correlation coefficient equation and had gotten 0.46. Is this correct? Also does this mean that it is a substantially high correlation or is it quite low?
