In descriptive statistics, the mean is simply the average of a set of data. The mode is that element that is most repeated in our data. Lastly the median is that value which divide the data into two equal parts, i.e, the 2nd quartile or 50th percentile of our data.

Mean is usually used to test the average performance of a group of element we investigate. e.g, the mean of the marks obtained by Math-2001 student at Wits univ. will indicate the average understanding of the whole Math-2001 learners. The median of this marks will tell us the middle mark, this mark has same number of element above and below it. Mode is that mark which most students had in common.
