Ameter is 100 centimeters, so a centimeter is one hundredth of a meter. a meter stick broke into two parts. one part was 0.37 meter long. how long was the other part?

The other part was 1-.37, or .63.  The other piece is 63% of the whole.
Since there are 100 centimeters, that would be 100*.63, or 63 centimeters.  The other part was 63 cm long.

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.
