When provided, the exact value for the test statistic or the exact probability was used in the calculation of the effect size.Family Planning Perspectives, 22,.* Google Scholar Howard,.Similarly, to ensure the independence of the data in the case of follow-up studies when multiple measurements were reported across time a single estimate of effect size was included.These names may imply differences in emphasis.( 1997 ) Needed: a ban on the significance test.The average effect size calculated for small-scale intervention was significantly higher than that for large-scale interventions (.26 and.01, respectively).It is not likely that this represents a decline in the quality of sex education interventions.Analyses of the effect sizes were conducted utilizing the D-stat software ( Johnson, 1989 ).Under those conditions, Q E follows an approximate 2 distribution with k p 1 degrees of freedom, where k is the number of effect sizes and p is the number of regressors ( Hedges and Olkin, 1985 ).Delivering high-quality comprehensive sexuality education requires training and support.Unfpa also advocates for policies on, and investments in, comprehensive sexuality education, both in and out of schools.
