Review on Power and Precision by Dexter Rasberry

The best part about this program is that it has a very user friendly interface. It's easy to navigate through, and the results are extremely accurate. I have found that it can sometimes be difficult to understand some of the calculations, but that could just be my lack of knowledge. I highly recommend using this program if you want an efficient way to calculate your sample sizes. It's also great to use if you're doing research in the medical field. This program allows me to quickly and accurately determine how many subjects should participate in a study.
