Question
Identify the class width, class midpoints, and class boundaries for the given frequency distribution.
Daily Low Temp (F) Frequency Daily Low Temp (F) Frequency
32-36 1 52-56 7
37-41 3 57-61 7
42-46 5 62-66 1
47-51 11
What is the class width? (type an integer or a decimal)
What are the class midpoints? (Use ascending order. Type integers or decimals.)
What are the class boundaries? (Use ascending order. Type integers or decimals.)
Explanation / Answer
The class width is w=36-32=4
The class mid points are (32+36)/2=34, 39,44,49,54,59,64.
The class boundary is the gap used to separate the classes that is 37-36=1
