Question

Determine which of the four levels of measurement (nominal, ordinal,interval,ratio)is most appropriate for the data .Alert system of yellow (lowest),orange,and red (highest) Choose the correct answer below.

A. The nominal level of measurement is most appropriate because tha data can not be ordered.

B. The ordinal level of measurement is most appropriate because the data can be ordered,but differences (obtained bysubtraction) can't be found meaningless.

C. The ratio level of measurement is most approriate because the data can be ordered. differences (obtained by subtraction) can be found and are meaningful,and there is a natural starting point.

D. The interval level of measurement is most appropriate because the data can be ordered,differences (obtained by subtraction) can be found and are meaningful,and there is no natural starting point.

Answer 1

Answer:

B

Step-by-step explanation:

Ordinal scale of measurement is suitable for alert system of yellow lowest to red highest because that has order red being the highest and yellow being the lowest. There are three categories of alert system that are

1. Red that indicates the higher level of threat

2. Orange that indicates the mild level of threat

3. Yellow that indicates the lower level of threat.

These three categories have order and mathematical operation applied on it will not meaningful. Hence, option B is correct.
