Use the same data set, but now use the SECOND SIDE. Arrange the data set. Data>Sort> Choose the second side and then click COMPUTE. You are to form a frequency table with 6 classes. 1.
What is the class width of the frequency distribution if you are to use 6 classes? 125
2. Form the frequency table.

Answer)
First we need to arrange the data in ascending order
55, 104, 179, 187, 189, 203, 204, 250, 250, 251, 260, 264, 265, 267, 267, 267, 270, 273, 273, 273, 273, 273, 273, 273, 273, 276, 278, 278, 284, 286, 288, 298, 298, 300, 301, 304, 317, 317, 320, 322, 340, 342, 343, 362, 367, 369, 409, 441, 452, 455, 503, 526, 567, 800
First we need to find range
Range is = highest value - lowest value = 800-55 = 745
Now we need 6 classes
So, width is = 745/6 = 124.16666666666 ~ 125
Classes. Frequency
55-180. 3
181-306. 33
307-432. 11
433-558. 5
559-684. 1
685-810. 1
As there are only 3 data values in between 55-180 so, frequency is 3
And so on.
