Correlations in maths
In correlational research, you investigate whether changes in one variable are associated with changes in other variables. After data collection, you can visualize your data with a scatterplot by plotting one variable on the x-axis and the other on the y-axis.

Still, it shows an important point about statistics: Correlation is not the same thing as causation — showing that one thing caused the other. Another complication: Many events or trends can have multiple causes.
