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. In this statistical index, the ratio of dispersion to a central criterion is measured. In fact, this index shows how much the standard deviation of the values changes per unit of change in the […]
Descriptive statistics indices, such as Central Tendency indices or dispersion measures, are used to identify the statistical population. But using each one alone may not have a good result. Simultaneous attention to the criteria of concentration and dispersion helps the statistical population to be better known and its behavior can be compared and analyzed. they […]
As in the calculation formula Average said, the role of each observation and value in calculating the average is equal and the same. If it is necessary that some observations have more or less importance in calculating the mean, weight (importance level) can be considered for them. In this article from Arman Computer Magazine, we […]
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 […]
