Regroup tens as hundreds

35 tens

tens = 10 ones = 0.1 hundreds

35 tens = 350 ones = 3.5 hundreds

So 35 tens = 3.5 hundreds

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.
