The objective of every experiment is to establish a solution to a particular problem. If, for instance, you want to determine which variable influences the other, you got to experiment, and from there, you can establish a dependent from an independent variable. This is a detective science test; give it a try and have fun!

### Which of the following is a quantitative observation?

• A.

The car is a green Honda CRV.

• B.

There are two people sitting in the car.

• C.

The car is traveling at 45 mph.

• D.

There is one bumper sticker on the back of the car.

C. The car is traveling at 45 mpH.
Explanation
The quantitative observation in this question is "The car is traveling at 45 mph." This is a quantitative observation because it provides a specific numerical value (45 mph) to describe the car's speed. The other options provide qualitative observations, such as the color of the car, the number of people in the car, and the presence of a bumper sticker, which do not involve numerical values.

Investigate

• B.

Conclusion

• C.

Hypothesis

• D.
