Answer: B.The ratio level of measurement does not apply.
Explanation:
Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables.
In statistics , the level of measurement is a categorization of nature of information given regarding the variables in the data.
There are 4 scales of measure :
1. Nominal scale
→ Classify the data on the basis of the attributes such as religion, gender , etc.
2. Ordinal scale
→ Order the variables according to their ranks such as first , second ,third and so on.
3. Interval scale
→ Measure the difference between any two categories. It uses the actual value assigned to the variable not the relative. For ex : 0 degree Celsius does not mean there is no temperature. .
4. Ratio scale :
→ Preserves all the characteristics of above scales in addition to that , it uses the actual meaning of 0. For example : Age.
Given statement : A movie with a 4-star rating is twice as good as one with a 2-star rating.
Since , the rating given to movie is basically a process to arrange movies in to order (For example : bad , okay , good , very good and perfect).
If a movie with a 4-star rating is twice as good as one with a 2-star rating.
Then, we basically measuring the distance between them , so it belongs to interval scale not ratio .
So , the correct answer is :
The ratio level of measurement does not apply.
