You go to Mellow Mushroom and your bill is $50. You decide to leave a 20% tip.
What is your final cost?

60$

10% of 50$ is 5(50/10), so 20% (10% x 2) would be 10 (5$ x 2)

The original 50$ added to the 10$ would make 60$

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.
