Sample Size for Evaluating Treatment Effects on Red Pine Seedlings
Basal diameter and total height measurements of 990 3-0 red pine seedlings provided the variance data to compute sample sizes for various probabilities and allowable errors. A precision level ± 5 percent of the mean would require approximately 20 to 100 seedlings, depending upon the probability level chosen.
