Answer :

To answer the question, we need to correctly match each item from COLUMN A with its corresponding definition from COLUMN B.

Let's go through each item step-by-step:

1. 2.2.1 Sample size:
- D: A percentage of the total population in statistics.
- Explanation: In statistics, a sample size often represents a fraction or percentage of the total population being studied.

2. 2.2.2 Population:
- E: A well-defined collection of individuals or objects known to have similar characteristics.
- Explanation: A population in statistics refers to an entire collection of individuals or objects that are being studied, possessing specific shared characteristics.

3. 2.2.3 Likelihood:
- B: The chance that something will happen.
- Explanation: Likelihood refers to the probability or chance that a particular event will occur.

4. 2.2.4 Questionnaire:
- A: A tool consisting of questions for the purpose of gathering respondents.
- Explanation: A questionnaire is a research tool made up of a series of questions used to collect information from respondents.

5. 2.2.5 Mean:
- C: It gives a very good idea about the central tendency of the data being collected.
- Explanation: The mean (or average) provides a measure of the central tendency of a set of data, summarizing the data with a single value.

Based on the provided information, the final answer would be:

[tex]\[ \begin{aligned} &\text{2.2.1 Sample size} &\rightarrow& \text{D} \\ &\text{2.2.2 Population} &\rightarrow& \text{E} \\ &\text{2.2.3 Likelihood} &\rightarrow& \text{B} \\ &\text{2.2.4 Questionnaire} &\rightarrow& \text{A} \\ &\text{2.2.5 Mean} &\rightarrow& \text{C} \\ \end{aligned} \][/tex]

Thus, the answers are:
- 2.2.1: D
- 2.2.2: E
- 2.2.3: B
- 2.2.4: A
- 2.2.5: C
