Question

determining frequency for a histogram
consider the data set shown below.
42, 43, 46, 47, 47, 48, 49, 50, 51, 53, 55, 55, 59
to create a histogram of the data given, identify the frequency for the given intervals.
the interval 44 - 47 has a frequency of
the interval 48 - 51 has a frequency of
the interval 56 - 59 has a frequency of

Explanation:

Step1: Count data in 44 - 47

Check each number in the data - set 42, 43, 46, 47, 47, 48, 49, 50, 51, 53, 55, 55, 59. The numbers 46, 47, 47 are in the 44 - 47 interval. So the frequency is 3.

Step2: Count data in 48 - 51

The numbers 48, 49, 50, 51 are in the 48 - 51 interval. So the frequency is 4.

Step3: Count data in 56 - 59

The number 59 is in the 56 - 59 interval. So the frequency is 1.

Answer:

The interval 44 - 47 has a frequency of 3.
The interval 48 - 51 has a frequency of 4.
The interval 56 - 59 has a frequency of 1.
