Paper 1
Revise: CorrelationThe two variables are called co-variables. Each participant provides a pair of scores, such as their average hours of sleep and the number of caffeinated drinks they consume. Keeping these scores paired matters: comparing one person's sleep with another person's drink consumption would not show the relationship being investigated.
Paper 1, Paper 2
Either of the two variables measured in a correlation to investigate whether they are related; neither is manipulated.
Describe both the direction and strength of a correlation, then explain the relationship using the named co-variables.
For a DV or co-variable, state exactly what is measured and include the unit, time period or scoring rule where relevant.
In a correlation, call both measured variables co-variables; do not label them IV and DV.

A correlation investigates whether two measured variables are related. These are called co-variables. Unlike an experiment, the researcher does not manipulate one variable to see its effect on another: both are measured.
