Question

5.) A survey was administered to 30 randomly selected registered voters in Lake County to determine their political affiliation. The raw data is shown in the chart below. Organize the data by constructing a categorical frequency distribution.

D = Democrat, I = Independent, R = Republican, O = Other

D	O	R	D	D	D	R	I	D	I
O	R	R	I	D	D	R	I	O	D
R	D	D	I	O	D	D	R	D	D

Answer 1

We have four type of data variables, i.e. D = Democrat, I = Independent, R = Republican, O = Other

count each one of these variables in the given table and write down

D = 14, I = 5, R = 7, O = 4

total = 14 + 5 + 7 + 4 = 30

Percent for D = (number of D/total)*100 = (14/30)*100= 46.67

Percent for I = (number of I/total)*100 = (5/30)*100= 16.67

Percent for R = (number of R/total)*100 = (7/30)*100= 23.33

Percent for O = (number of O/total)*100 = (4/30)*100= 13.33

Class	Frequency	Percent
D	14	46.67
I	5	16.67
R	7	23.33
O	4	13.33
