A metaanalysis study reported a weighted average value of r

A meta-analysis study reported a weighted average value of r = 0.48 for the relationship between posttraumatic stress disorder and anger.

Based on correlation, how would your interpret the direction and strength of this relationship?

Solution

Sol)

From correlation if r=1 we say that the two variables are perfect positively correlated.

if r= - 1 we say that the two variables are negitively correlated.

if r=0 no correlation between them.

So from above analysis r=0.48. So we can say that there is positive correlation between posttraumatic stress disorder and anger.

We conclude that there is 48% correlation between posttraumatic stress disorder and anger.
