Question

For 108 randomly selected college students, the following IQ frequency distribution was obtained . construct a frequency histogram frequency polygon and ogive for the data( the data for this exercise will be used for exercise 2 - 31).
Class limits =90-98, 99-107, 108-116, 117-125, 126-134
Frequency=6, 22, 43, 28, 9

Answer 1

Histogram--this is obtained by plotting the frequency values of the data against the class limits.

frequency polygon is obtained by plotting the frequency values against the class midponts.

ogive is obtained by plotting the cumulative frequency values against the class upper bounds.
