This is my second post on dev.to. I plan to build a basic app calculating the mean from scratch without using any libraries. This evening or today, I will work on this program using either a data set or dummy data in a list. My goal is to write up this code today and post tonight or tomorrow. The program is very simple but powerful as I explain the methods used in the code. I plan to do a handful of simple apps each week and blog about them just to sharpen my skills and to keep up with my goal of blogging at least several times a week. I will extend this to calculating the variance and standard deviation from scratch as well. Some functions may be used to build the equation. The idea is to take basic statistical equations and work through them without using standard analytics libraries. Keep your eyes on the blog as I continue to write and put up code for you to follow, critique, and improve upon.
