Question

A poll solicits a large number of college undergraduates for information on the following variables: the name of their cell phone provider (AT&T, Verizon, and so on), the numbers of minutes used last month (200, 400, for example), and their satisfaction with the service (Terrible, Adequate, Excellent, and so forth). What is the level of measurement for each of these three variables?

Answer 1

1)Nominal:-the name of their cell phone provider (AT&T, Verizon, and so on),

2)Ratio:- the numbers of minutes used last month (200, 400, for example),

3) Ordinal:- (Terrible, Adequate, Excellent, and so forth).

Explanation:

The nominal level of measurement classifies data into mutually exclusive categories in which no order or ranking is imposed on the data set.

An example gathering information on college undergraduates base on the name of their cell phone provider (AT&T, Verizon, and so on).

The ratio level measures variables like time,weight, height, etc.

An example is the numbers of minutes used last month making phone calls by the college students. (200, 400, for example)

The ordinal level classifies data into categories that can be ranked (ordered)

Example ranking the satisfaction derived from the use of the service providers as (Terrible, Adequate, Excellent, and so forth).
