App Introductions

This is a data analyzing software. It can quickly calculate the average, median mode, variance and range.

I have learned about data analyzing such as mean, median, variance. In my daily life, I also need to calculate the average, median, mode, variance and range of a set of data, even using student calculators also take some time to compute, so I use math and JavaScript programming language knowledge to make this software for me to calculate and analyze a set of data easier.
