Explain why you should record a 1 in the tens column when you regroup in an addition problem?

think about it 1+2=3 so your answer is one plus anything just and one up!

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.
