Calculating the Mean (Disclaimer)

In posting today, I did not know the limitations on how to upload my screenshots of the program I explained. What I will do tomorrow is post the code within the post without screenshots from Visual Studio Code. However, it is still the coding environment for me and gives me everything I need without using a more feature-driven IDE like Visual Studio. So, I will post the raw code in my posts going forward. So, look for the corrected posts with some coding modifications tomorrow. I will eventually do some stuff with R as well. Both R and Python have democratized data science by allowing more people to use the language to analyze data.
