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.
