I looked into a few statistical analysis programs online and many of them were very confusing to me. I found one called Data Desk that seemed self explanatory. Using this program, it has a somewhat easy to figure out way to use it. It can use graphs, or excel sheets, and even scatter graphs. Another program I came across was called Analyse-It. In this program, it has similar packages like excel and scatter graphs. There was even a demo of a box-and-whisker graph. It can come up with the mean, df, P-value, and much more. It was somewhat visually appealing to me too. I think if I were to choose one site of the many out there, the main component of it would be it had to be easy to use and navigate through.
