What is the median of the set 1,5,8,10,11,12,14,17,19,21,22,23?

The median of this set is 13.

Explanation: we have 12 numbers, so we take the number between number 6 and 7 which are 12 and 14, between 12 and 14 we got 13, so that’s the median.

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.
