This video shows how to conduct a point-biserial correlation in SPSS. Point-biserial correlation is used when you have a dichotomous and a continuously measured variable.
Before you start, make sure that you know the labels of the dichotomous variable to interpret the results properly.
Example
=======
In my example I want to correlate gender and weight.
Male participants are coded as 0 and female participants as 1.
This will be important when it comes to interpretation.
