QUALITATIVE VS. QUANTITATIVE OBSERVATIONS

Definitions Recap:
- Quantitative observations involve numbers or measurements (e.g., “30 students,” “98 pounds”).
- Qualitative observations describe qualities or characteristics without numbers (e.g., “it smelled good,” “it was green”).

---

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

1. Quantitative — The cup had a mass of 454 grams.
→ *Reason: “454 grams” is a specific numerical measurement.*

2. Quantitative — The temperature outside is 25° C.
→ *Reason: “25° C” is a measured value with units.*

3. Qualitative — It is warm outside.
→ *Reason: “Warm” is a descriptive term, not a number.*

4. Quantitative — The tree is 30 feet tall.
→ *Reason: “30 feet” is a numerical measurement of height.*

5. Quantitative — The building has 25 stories.
→ *Reason: “25” is a countable number.*

6. Qualitative — The building is taller than the tree.
→ *Reason: This is a comparison, not a specific number. No measurement given.*

7. Qualitative — The sidewalk is long.
→ *Reason: “Long” is a relative description, not a number.*

8. Quantitative — The sidewalk is 100 meters long.
→ *Reason: “100 meters” is a precise measurement.*

9. Qualitative — The race was over quickly.
→ *Reason: “Quickly” describes speed in a subjective way, no time unit given.*

10. Quantitative — The race was over in 10 minutes.
→ *Reason: “10 minutes” is a specific time measurement.*

CONSTRUCTING INFERENCES FROM OBSERVATIONS

Definitions Recap:
- Observation (O): Something you can directly see, hear, touch, smell, or measure — factual and objective.
- Inference (I): A conclusion or interpretation based on observations — involves reasoning or assumption.

---

Indicate your answer with either the letter "O" for an observation or the letter "I" for an inference.

1. I — It is summertime.
→ *Reason: You don’t directly observe “summertime.” You infer it from clues like warm weather or school being out.*

2. O — It is daytime.
→ *Reason: You can directly observe daylight, sun position, etc. — it’s a direct sensory observation.*

3. O — They saw birds.
→ *Reason: This reports what they visually perceived — direct observation.*

4. I — They saw seagulls.
→ *Reason: Identifying the type of bird (“seagulls”) requires knowledge or inference — unless you’re an expert, you’re inferring the species from appearance.*

5. I — They went swimming.
→ *Reason: You didn’t necessarily see them swim; you might infer this from wet clothes, towels, or location. Not directly stated as observed.*

6. I — One friend’s name was Bob.
→ *Reason: Names aren’t observable traits — you must be told or infer from context (e.g., someone called him Bob).*

7. I — It was a warm day.
→ *Reason: “Warm” is a qualitative judgment — you infer it from feeling or thermometer reading. But since it’s a perception, not a direct measurement, it’s often considered an inference unless a temp is given.*

8. O — The birds were black and white.
→ *Reason: Color is directly observable — you can see the birds’ feathers.*

9. I — They ate lunch and drank Coca-Cola.
→ *Reason: You didn’t witness them eating or drinking — you infer this from seeing food wrappers, bottles, or their behavior.*

10. I — The people are friends.
→ *Reason: Friendship is a relationship you infer from interaction, conversation, or behavior — not something you can directly observe.*
