Identify the scale interval on the frequency data axis?
15
20
Zero
10
Starting point is 0
Next point is 20
Thus, Interval = 20 - 0 = 20
The ______ axis has a scale that is a measure of the frequency or amounts of the different data groups.
Construct a frequency distribution with a class interval of 4 on exclusive basis for the following data:
91, 94, 111, 121, 95, 103, 99, 110, 100, 101, 92, 105, 110, 111, 93, 96, 98, 106, 94, 115
