Question

Use equal intervals to make a frequency table for the average number of movies per person. You do not need to show tally marks.

Answer 1

The frequency table would look something like this:

# countries | average # of movies
          1       |                 0-1
          5       |                 1-2
          5       |                 2-3
          2       |                 3-4
          1       |                 4-5

We set equal intervals for the number of movies.  Then we count the frequency, or number of entries, for each interval.
