The frequency distribution below was constructed from data collected from a group of 25 students.

Height
(in Inches)
Frequency
58 - 63 3
64 - 69 5
70 - 75 2
76 - 81 6
82 - 87 4
88 - 93 3
94 - 99 2

a. Construct a relative frequency distribution.
b. Construct a cumulative frequency distribution.
c. Construct a cumulative relative frequency distribution

Answer:

a)

Relative Frequency Distribution:

A relative frequency distribution is obtained by using the formula.

Relative frequency=f/n.

b)

Cumlative frequency distribution:

We have to add all the previous relative frequencies to the relative frequency for the current row.

c)

Cumulative relative frequency distribution:

The cumulative relative frequency is obtained by using the formula is

Cumulative relative Frequency=Cumulative frequency/sample size.

Because of rounding, the relative frequency column may not always sum to one and the last entry in

the cumulative relative frequency column may not be one, they each should be close to one.
