A correlational study found a statistically significant relationship, r(56) = 0.62, p < 0.05. What is the size of the treatment effect? Answer in words and a number. And what does it mean?

Solution

As relationship is statistically significant, there is a correlation between the two variables. i.e. correlation is not 0.

p <0.05 means we reject null hypothesis that r =0

We accept alternate hypothesis that r not equal to 0

As r = 0.62, there is a positive correlation higher than average between the two variables.
