Tell me if the number is rational or irrational..
the square root of 40/10
8 pi
1/6
0.3 (three is repeating)

1. Rational comes out even. 2. Irrational 8 square rooted doesn't come out even. 3. Irrational 6 square rooted doesn't come out even. 4. .3 square rooted doesn't come out even.

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.
