A function contains 6 ordered pairs. Five of the ordered pairs are shown below. (15, 21), (17, 26), (21, 37), (25, 40), and (30, 45)
What would be the 6th ordered pair?

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.

Im pretty sure it would be 6 purple rectangles.
