Mrs. Dugan plans to serve 100 barbecue sandwiches at the campany picnic. How many packages of barbecue buns will she need if buns come in packages of 8? Packages of 12? Help me i don't get it please

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.
