Although the difference in projected estimations did not reach statistical significance, the effect size suggests that the lack of statistical significance is the function of the interplay between the small sample and large variance ( F (2,19) = 1.053; p = 0.372; η 2 = 0.116), resulting in the test being underpowered to reject the null hypothesis when the difference between the three groups may exist.
