sample size in the Output Parameters box on the right side. 1. F test family: A researcher wants to use a one-way ANOVA (fixed effects). The researcher expects to find an effect size (f) of 0.25 using an error probability (a) of 0.05. He wants the power of his study to be 0.80. The research design includes 4 groups. 2. T-test family: Another researcher wants to analyze the correlation (point-biserial model) for a 1- tailed test with an expected effect size (p) of 0.35 using an error probability (a) of 0.05. She wants the power of her study to be 0.80. 3. F test family: A group of researchers wants to use linear multiple regression (fixed model, R2 increase). They expect to find an effect size (f2) of 0.05 using an error probability (a) of 0.01. They want the power of their study to be 0.85. Their model has 4 predictors and they are testing all 4 predictors in this model. 4. F test family: A group of researchers want to use a MANOVA (repeated measures, between factors). They expect to find an effect size of 0.18 using an error probability (a) of 0.05. They want the power of their study to be 0.80. The research design includes 4 groups and they are planning on having 8 separate measurement occasions. They anticipate the correlation among the repeated measures to be 0.15
