The IQ score and brain volume are listed for each of five different subjects. Refer to the table of measurements below. Given that the data are matched and considering the units of the data, does it make sense to use the difference between each IQ score and brain volume that is in the same column? Why or why not?

### IQ Score and Brain Volume Analysis

The IQ score and brain volume measurements are listed for five different subjects. Refer to the table of measurements below:

| Subject | 1   | 2   | 3   | 4   | 5   |
|---------|-----|-----|-----|-----|-----|
| **IQ Score** | 88 | 101 | 99  | 86  | 99  |
| **Brain Volume (cm<sup>3</sup>)** | 1096 | 1035 | 1000 | 1030 | 1165 |

Given that the data are matched and considering the units of the data, does it make sense to use the difference between each IQ score and brain volume that is in the same column? Why or why not?

#### Answer Options:
Choose the correct answer below.

- **A.** Yes, it does make sense to use the difference between each IQ score and brain volume in the same column, because they are measurements obtained from the same person.
  
- **B.** No, it does not make sense to use the difference between each IQ score and brain volume in the same column, because the terms should be added.
  
- **C.** Yes, it does make sense to use the difference between each IQ score and brain volume in the same column, because high IQ is caused by large brain volume.
  
- **D.** No, it does not make sense to use the difference between each IQ score and brain volume in the same column, because IQ scores and brain volumes use different units of measurement.

**Explanation:**

- The table presented includes five subjects with their respective IQ scores and brain volumes measured in cubic centimeters (cm<sup>3</sup>).
- It's important to consider that IQ scores and brain volumes are measured in different units. IQ score is a unit-less measure, typically on a standardized scale, while brain volume is measured in cubic centimeters.
- The primary question addresses whether it is sensible to use the difference between these two different measures within the same individual to draw any meaningful conclusions.

For accurate analysis and understanding, consider not only the numerical values but also the scientific relevance and the units of measurement.
