10 cards from this deck
The connection between two variables shown on a scatter graph
Both variables increase together; uphill pattern left to right
One increases while the other decreases; downhill pattern
No clear pattern; points randomly scattered with no relationship
Points form fairly straight line, close to line of best fit
Pattern exists but points more spread out from line of best fit
Predictions within the range of existing data (more reliable)
Predictions outside the range of data (less reliable)
A data point that doesn't fit the general pattern
No - correlation doesn't prove one variable causes the other
