Frequency Table

Example

For the given values below, make a frequency table.
Use 5 intervals starting from 50-59.

81, 56, 74, 52, 78, 81, 77, 91, 85, 60,
75, 69, 97, 84, 70, 67, 80, 74, 74, 88

Solution

81, 56, 74, 52, 78, 81, 77, 91, 85, 60,
75, 69, 97, 84, 70, 67, 80, 74, 74, 88

Interval	Frequency
50-59	2
60-69	3
70-79	7
80-89	6
90-99	2

50-59
Count the number of the values in 50-59.
56, 52 → Frequency: 2
...

Example

For the given frequency table,
find the number of values that are less than 80.

Interval	Frequency
50-59	2
60-69	3
70-79	7
80-89	6
