Correct

In fact, for a continuous variable, a grouped frequency
distribution is needed, rather than a frequency distribution.
This is because, with a continuous variable, there are
theoretically an infinite number of scores between the
lowest and highest score. In a frequency distribution of a
discrete variable, or one with 25 or fewer scores, all of the
scores can be shown. But not all of the theoretically infinite
scores can be shown for a data set of a continuous variable.
Thus, grouping is necessary.
