@Wait 0.5
@at ,+4
The first column in the tally
table shows the #bclasses#
of the data you are recording. Here, the classes
are examination scores.
@Wait 0.5
@at ,+4
For example, scores between 61 and 70 are in
the same class.  For each score in the list of
raw data, find the corresponding class in the
tally table and make a tally mark in the tally
column next to it.

@Wait 0.5

Adding up all the tally
marks for each class
gives the #bfrequency# of that class. For
example, there are 8 scores in the 51-60 class,
so we say this class has a frequency of 8.
@Wait 0.5
The frequency column shows the #bfrequency#
#bdistribution# for the set of data. For grouped
data, we say that the frequency column shows
the #bgrouped distribution# of the data.

@Wait 0.5
@At ,+10
   Upper bound = #B60.4#     Lower bound = #B51.5#


@Wait 0.5

(Classes should be of equal width.)
