What are the coordinates of A (1, 2), B (3, 4), and C (5, 6) after a reflection over the x-axis?

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.
