Question

statistics
constructing a frequency distribution for grouped data
here are the hottest recorded temperatures (in °f) for eight cities throughout north america.
complete the grouped frequency - distribution for the data.
in the distribution, the frequency of a class is the number of temperatures in that class.
(note that we are using a class width of 5.)
temperature (in °f)
105 117 105 105
109 112 114 103
temperature (in °f) frequency
103 to 107
108 to 112
113 to 117

Explanation:

Step1: Count values in 103 - 107

The values 103, 105, 105, 105 in the data set fall in the range 103 - 107. So the frequency is 4.

Step2: Count values in 108 - 112

The values 109, 112 in the data set fall in the range 108 - 112. So the frequency is 2.

Step3: Count values in 113 - 117

The values 114, 117 in the data set fall in the range 113 - 117. So the frequency is 2.

Answer:

Temperature (in °F)	Frequency
108 to 112	2
113 to 117	2
