  1. The value of the corresponding effect size r square is 0.3025

    How to solve for the effect size

    We have correlation to be given as  0.55
    Then r squared = 0.55
    Then we would have
    r = 0.55 x 0.55
    = 0.3025
    Hence we conclude that if A researcher finds a correlation of 0.55 between an x and a y variable. assume alpha = .05 and a one-tailed test, the value of the corresponding effect size is 0.3025.
