by cohen's d three averages are away from one another.

effect size allows us to measure the magnitude of mean differences. This is usually calculated after rejecting the null hypothesis in a statistical test. If the null hypothesis is not rejected, effect size has little meaning.

cohen's d= $\frac{X_{1} -X_{2} }{\sqrt{S^{2}_{P} } }$

With cohen's d, remember that:

d = 0.2, small effect

d = 0.5, medium effect

d = 0.8, large effect

therefore, by cohen's d three averages are away from one another.
