Answer 1

Question 1

Answer:

nominal, interval, nominal, interval, nominal

Step-by-step explanation:

Levels of measurement are used to properly define the characteristics of variables of interest in a statistical study.

A variable is a quantity that varies across a population of interest.

Different levels of measurement are listed below:

- nominal scales has to do with naming or labelling. The assigned label cannot be quantified. They are not arranged in order

- ordinal scale is when variables are labelled and arranged in a particular order

- interval involve a specific interval between the variables in addition to labelling and order

- ratio is a scale that bears all the characteristics of interval scale in addition to having a value of zero for variables that don't exist.

From the question

1. Make/ Model, is nominal

2. Miles per Gallon, is interval

3. Car Type (e.g., economy, full size), is nominal

4. Price, is interval

5. Color, is nominal

Question 2

Answer:

Ratio

Step-by-step explanation:

Price of $59 is a ratio scale because there is a specific interval that exists between each dollar in the scale, and there is an arbitrary zero value for money.

Zero value of money means absence of money.

For example difference between $59 and $65 is $6 which is measured in specific $1 amounts
