I frequently asked the below question from my students:

'Do I You need Statistics to learn R Programming?'

The answer is, NO. If you want to learn R programming only, Stat is not required. You can be an expert R programmer without knowing anything of Stat because R is a language where lot of APIs are provided for Statistical calculations and Visualization.

But, if you want to get the flavour of Big Data Analysis and Data Visualization, basic Stat knowledge will help. If you want to be a Data Scientist, Stat is very much required. In this case, I will suggest you to take a Stat course before starting R Programming learning or in parallel.

What is Assume Mean Method?

Chandan Singh

Tutor

In statistics the assumed mean is a method for calculating the arithmetic mean and standard deviation of a data set. It simplifies calculating accurate values by hand. Its interest today is chiefly historical but it can be used to quickly estimate these statistics.
