Empowering Computer and Statistics
In other articles from Arman Computer Magazine, we have examined how to calculate the average and weighted mean. But in this text, we want to discover the average or mean formula and learn how to derive its formula. I try to mention the formula syntax less, but sometimes it is necessary to use the syntax […]
“Coefficient of Variation” (CV) is suitable for comparing the dispersion (Variation) of two groups of data collected with different measurement units.

The statistical approach to random numbers is very particular. In gambling and games of chance, random numbers have the main role. So, in a sequence of posts in Armancomputer magazine, I will discuss probability distribution and introduce some commands in R language, to generate random numbers from the main statistical distributions such as Normal, Uniform, […]
The word mean is used a lot in today’s life. Although these words are from specialized keywords mathematics and Arman Computer Magazine, we discuss the concept of average and its applications. The arithmetic mean, average, or average all refer to a type of statistical calculation that is included in the group of central statistical indicators […]
