Reference: OCR
The two variables measured from the same participants, each carrying its name and units on an evenly scaled axis of the scatter diagram.
Two continuous variables plotted on a scattergram to display the relationship between them, rather than a difference between conditions.
Two things that already vary and are measured by the researcher, who asks how they vary together while manipulating nothing.
Both are measured as they are found and neither is manipulated, so there is no independent or dependent variable.
The two measures in a correlation, both of which are measured rather than manipulated.
