Let’s go step by step to match each definition in Column A with the correct term from Column B.

We’ll read each sentence carefully and think about what it means, then pick the best matching word.

---

1. The number in a set of data that occurs the most.
→ This is called the Mode.
Example: In {2, 3, 3, 5}, the mode is 3 because it appears twice.
✔ Match: I. Mode

---

2. The average of a data.
→ “Average” usually means the Mean (add all numbers, divide by how many).
✔ Match: J. Mean

---

3. It is the number separating the upper half from lower half. It is the middle of the data set.
→ That’s the Median.
Example: In {1, 2, 3, 4, 5}, median is 3.
✔ Match: G. Median

---

4. It is the measure of the amount of variation.
→ Variation = how spread out the data is → this is Standard deviation.
✔ Match: D. Standard deviation

---

5. Collection of Data
→ Simple! That’s just a Data Set.
✔ Match: F. Data Set

---

6. It is the measure of the asymmetry of the probability distribution.
→ Asymmetry = skewness. If data leans left or right, it’s skewed.
✔ Match: A. Skewness

---

7. It is the difference between highest and lowest value.
→ That’s the Range.
Example: {1, 5, 9} → range = 9 - 1 = 8
✔ Match: C. Range

---

8. Is the type of data whose value is measured in the forms of numbers.
→ Numbers you can measure or count → Quantitative Data
✔ Match: B. Quantitative Data

---

9. It is used to describe the variability in a sample or population.
→ Variability = how much things differ → again, Standard deviation fits here too? Wait — but we already used D for #4. Let’s check…

Actually, look at Column B: E is “Measure of spread”. That’s a general term that includes standard deviation, range, etc. But #4 specifically says “measure of the amount of variation” — which is often standard deviation. #9 says “describe the variability” — also could be standard deviation. Hmm...

Wait — let’s re-read:

#4: “measure of the amount of variation” → typically standard deviation

#9: “used to describe the variability in a sample or population” → still sounds like standard deviation... but maybe they want “Measure of spread” as a broader term?

But note: Column B has both D (Standard deviation) and E (Measure of spread). So perhaps:

- #4 → D (specific measure)
- #9 → E (general category)

That makes sense. Because “measure of spread” is a group that includes standard deviation, range, IQR, etc.

So:
✔ #9 → E. Measure of spread

---

10. It is the type of data that can be observed and recorded.
→ Not numerical — like colors, names, categories → Qualitative Data
✔ Match: H. Qualitative Data

---

Now let’s list all matches clearly:

1 → I
2 → J
3 → G
4 → D
5 → F
6 → A
7 → C
8 → B
9 → E
10 → H

Double-checking no duplicates and all terms are used once:

Column B: A, B, C, D, E, F, G, H, I, J — all matched exactly once. Perfect.

Final Answer:
1-I, 2-J, 3-G, 4-D, 5-F, 6-A, 7-C, 8-B, 9-E, 10-H
