Question

qualitative observations vs. quantitative observations worksheet
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. i 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. a. qualitative
2. the temperature outside is 250° c. b. quantitative
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.
7. the sidewalk is long.
8. the sidewalk is 100 meters long.

Explanation:

Quantitative observations have numerical values for measurement. Qualitative observations describe qualities without numbers. We check each statement for numerical measurement.

1. Mass is given numerically (454 grams), so it's quantitative.
2. Temperature is given numerically (250°C), so it's quantitative.
3. "Warm" is a descriptive quality without a numerical value, so it's qualitative.
4. Height is given numerically (30 feet), so it's quantitative.
5. Number of stories is given numerically (25), so it's quantitative.
6. "Taller" is a comparative quality without a specific numerical value, so it's qualitative.
7. "Long" is a descriptive quality without a numerical value, so it's qualitative.
8. Length is given numerically (100 meters), so it's quantitative.

3. A. Qualitative
4. B. Quantitative
5. B. Quantitative
6. A. Qualitative
7. A. Qualitative
8. B. Quantitative
