What is the median of the data set 36,48,67,91

The median is the number in the middle of a data set when the data set is in numerical order.

36,48,67,91

There is an even amount of numbers, so you take the two middle ones (48 and 67) and find the average of the two. So, (48 +67) / 2
                                                                              115 / 2
                                                                                 57.5
The median of the data set is 57.5  .

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
