QUALITATIVE VS. QUANTITATIVE

All of the observations in this worksheet were qualitative; that is, you observed a quality about an object (it smelled good, it was green, etc.). Another type of observation is quantitative, meaning that it can be described or measured in concrete numerical terms. The following observations are quantitative: There are 30 students in my class. I weigh 98 pounds. 1 ate a pound of potatoes.

Determine which of the following statements are quantitative and which are qualitative.

1. ______The cup had a mass of 454 grams.

2. ______The temperature outside is 25 degrees C.

3. ______It is warm outside.

4. ______The tree is 30 feet tall.

5. ______The building has 25 stories.

6. ______The building is taller than the tree.
