Which expression represents the calculation the sum of x and 8 is divided by 6?

(x+8) / 6. X + 8 is in parenthesis, because it must be done before dividing by 6.

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.
