Correct

The two types of distributions are quite different, although
both convey similar information. A frequency distribution
shows each specific score. However, a grouped frequency
distribution includes a range of scores in each group rather than
each specific score. Thus, we cannot see the specific scores in
the grouped frequency distribution--specific scores that are
needed in order to construct a frequency distribution. We
would have to go back and look at the original data. We can
convert a frequency distribution to a grouped distribution,
without looking at original data, but not the other way around.
