Question

determining frequency for a histogram
consider the data set shown below.
42, 43, 46, 47, 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 interval

Count numbers \(44\leq x\leq47\). Data: \(46,47,47\). Frequency is \(3\).

Step2: Count data in 48 - 51 interval

Count numbers \(48\leq x\leq51\). Data: \(48,49,50,51\). Frequency is \(4\).

Step3: Count data in 56 - 59 interval

Count numbers \(56\leq x\leq59\). Data: \(59\). Frequency is \(1\).

Answer:

The interval \(44 - 47\) has a frequency of \(3\), the interval \(48 - 51\) has a frequency of \(4\), and the interval \(56 - 59\) has a frequency of \(1\).
