Use equal intervals to make a frequency table for the average number of movies per person. You do not need to show tally marks.
To create a frequency table for the average number of movies per person using equal intervals, we can group the data into different intervals and count the number of countries falling within each interval. Here is the frequency table:
Interval Frequency
--------------------
0.5 - 1.0 | 2
1.0 - 1.5 | 3
1.5 - 2.0 | 2
2.0 - 2.5 | 3
2.5 - 3.0 | 2
3.0 - 3.5 | 2
3.5 - 4.0 | 0
4.0 - 4.5 | 1
In this table, the left endpoint of each interval represents the lower limit of the interval, while the right endpoint represents the upper limit of the interval. The frequency column shows how many countries fall within each interval.
Average Number of Movies Per Person | Frequency
--------------------------------------|---------
0.5 - 1.0 | 1
1.0 - 1.5 | 2
1.5 - 2.0 | 3
2.0 - 2.5 | 3
2.5 - 3.0 | 2
3.0 - 3.5 | 0
3.5 - 4.0 | 0
4.0 - 4.5 | 1
