How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Mean vs Median. The mean and median are measures of a collection of data related to any single source information. We use mean and median to check the location of the data because they give an indication of a central value around which a set of values tends to cluster. Mean is the sum of total values in a data divided by number of values, while median is the middle value of a data. The selection of either mean or median for examining the data depends upon the type of data and requirement of result, as in some cases mean gives better results than median and vice versa.
