However, the method to calculate the arithmetic mean can vary based on the frequency of each variable in the data set — simple average equally weighted or weighted average. The formula for the arithmetic mean for equally weighted variables can be derived by summing up all the variables in the data set and then divide the result by the number of variables. Mathematically, it is represented as,. In case of unequally weighted variables, the formula for the arithmetic mean can be derived by summing up the products of each variable and its frequency and then the result is divided by the sum of the frequencies.
