This activity will help you to...
· Interpret correlations from coefficients and scattergrams
· Understand the relationship between coefficients and scattergrams
Activity: Here are some scattergrams and the correlation coefficients that
correspond to them. Try matching them up.

What is a correlation coefficient?
A correlation coefficient is a statistic that describes the relationship between
two sets of paired data.. The correlation coefficient tells you essentially the
same thing as a scattergram, namely: whether two variables are related; if so, how
strongly; and whether the relationship is positive (as one rises so does the other) or neg-
ative (as one rises, the other falls). Correlation coefficients are always numbers be-
tween -1 and +1. They are interpreted as follows:
