Determine Sample Size Power Analysis. Basically every scientific discipline. For unequal ns use.
It goes hand-in-hand with sample size. Statistical power analysis is an important technique in the design of experiments that helps a researcher to determine how big a sample size should be selected for that experiment. Power analysis accomplishes this by examining the relationship among six variables.
Cohen suggests that h values of 02 05 and 08 represent small medium and large effect sizes respectively.
