Correlations
Investigates the relationship between two variables; co-variables (two measured variables)
Display of correlations: Scattergram → A graphical representation of the correlation
between two sets of scores.
Example:
Types of correlation:
Positive correlation: Height + weight = both increases
Negative correlation: Smoking (increase) + Life expectancy (decreases)
No correlation: Shoe size + IQ = (None)
