It can be used with both discrete and continuous data, although its use is most often with continuous data. In this case the mean is 21.52. The median is the middle score for a set of data that has been arranged in order of magnitude. The median statistic is 21.26. The mode is the most frequent score in our data set. On a histogram it represents the highest bar in a bar chart or histogram. You can, therefore, sometimes consider the mode as being the most popular option. In this case there is no mode provided in the data.
