Section 6.1 - Confidence Intervals for the Mean (Large Samples)
... (c) Interval estimate: an interval (range of values) used to estimate a population parameter. Although the point estimate is not likely exactly µ, it’s probably close (margin of error). (d) Level of confidence c: the probability that the interval estimate contains the population parameter. (e) Criti ...

... However, this assumes we know the R-squares or equivalently the effect sizes. Cohen defined small, medium, and large effect sizes as corresponding to values of .02, .15, and .35, respectively. Thus, it directly follows that the required sample sizes to have a power of .80 to detect small, medium, a ...
