Sample mean symbol x bar5/5/2023 ![]() ![]() The majority of the mathematical applications use the term average which automatically means to calculate the mean. The first one is called the mean, which is sometimes used instead of the term “average”, second is the median, and third is the mode of the data. Throughout the years and after plenty of research and study, mathematicians were able to deduce three convenient ways of calculating the average of a set of data. In mathematics or statistics, if you want to find the average of any data you have to find the sum of all the values and then divide the summed up value by the total number of values in the given data. Another meaning of average can be “the mean value that is equivalent to the ratio between the total numbers of a specific set and the total numbers in the given set”. In other words, the average is the midpoint or central point of any data. We can define average as the fraction of the summation of whole data to the number of units.
