Question

A is a summary description of a characteristic or measure of the sample. It is used as an estimate of the population parameter.

• A. statistic
• B. precision level
• C. finite population correction
• D. parameter

Hint:

Sample ⇒ Statistic (estimate); Population ⇒ Parameter (true value).

Answer 1

The Correct Option is A

Step 1: Recall the definitions.
- Statistic: A numerical measure calculated from sample data. Serves as an estimator of the unknown population parameter.
- Parameter: Population measure.
Step 2: Link to stem.
The stem clearly states “measure of the sample … estimate of the population parameter” — that is the textbook definition of a statistic.
Step 3: Eliminate distractors.
- (b) Precision level: relates to allowable error.
- (c) Finite population correction: variance adjustment term.
- (d) Parameter: refers to population, not sample. \[ \boxed{(a)} \]
