5/8 x 4/15 = ? give me some here and if the answer is not correct i will take it down : )

You have to multiply straight across and straight on the bottom.
5 x 4 = 20 and 8 x 15 = 120

So, the answer is 20/120 and after you simplify it, it will be 1/6.

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.
