Answer 1

Answer:  B.The ratio level of measurement does not apply.

Step-by-step 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.
