Survey using a Nominal Variable

STATS-WLYEL1

A survey was conducted about people's political party preferences. One of the questions asked people to identify themselves as a democrat or republican. After the survey was completed a frequency table was used to show the result.

This question is flawed because:

A

the categories are not exhaustive.

B

the categories are generally mutually exclusive.

C

people generally don't know their political preference.

D

political preference is a quantitative variable.
