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 4.
the interval 56-59 has a frequency of 1.
(histogram with x-axis labeled intervals: 40-43, 44-47, 48-51, 52-55, 56-59; y-axis labeled frequency: 0-8)

Explanation:

Step1: Count data in 44-47

Identify values: 44,46,47 → Count = 3

Step2: Confirm 48-51 count

Identify values: 47,48,49,50,51 → Wait, correct values: 48,49,50,51 → Count = 4 (matches given)

Step3: Confirm 56-59 count

Identify value: 59 → Count = 1 (matches given)

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
