Michael mowed 3/4 of the lawn. Andy mowed 1/2 of what was left. What fraction of the total lawn did Andy mow?

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.

What’s your question.
