Practical Significance in Early Intervention Research: From Affect to Empirical Effect.
Ottenbacher, Kenneth J.
Journal of Early Intervention, v16 n2 p181-93 Spr 1992
Measures of effect size were computed for 237 statistical tests from 59 early intervention studies. Data revealed that the average treatment effect across studies was medium in size. Interpretation of measures of magnitude strength is discussed in relation to statistical significance testing. Reporting of measures of effect size along with traditional quantitative results is encouraged. (Author/JDD)
