Table - 10


Example
: The following gives the weights (to the nearest pounds) of 40 students of the 7th grade. Construct a frequency distribution table giving frequencies and cumulative frequencies of two types. Tabulate the data into equal classes, the 1st class being 118 - 122. Also indicate the class boundaries and the class-marks.

144, 125, 149, 157, 132, 150, 164, 138,

146, 158, 140, 147, 168, 126, 138, 176,

136, 148, 142, 144, 163, 119, 154, 165,

146, 173, 161, 145, 135, 142, 142, 147,

135, 153, 140, 135, 150, 156, 128, 145


Solution : The successive classes are 118 - 122, 123 - 127, ....., 173 - 177. The lower and upper class boundaries for the 1st class will be 117.5 and 122.5 and the class-mark will be

The class-boundaries and the class-marks will go on increasing by 5.
