Question

The measurement of sampling error is usually called:

• A. Significance level
• B. Confidence level
• C. Precision of sampling plan
• D. Validation of data

Hint:

Precision of sampling plan = how close your sample gets to the true population value, measured by standard error.

Answer 1

The Correct Option is C

Step 1: Significance level relates to hypothesis testing decisions, not sampling error size, eliminate.
Step 2: Confidence level describes interval reliability, not the error magnitude, eliminate.
Step 3: Validation of data checks accuracy, unrelated to sampling error, eliminate.
Step 4: Precision of a sampling plan directly measures how close estimates cluster to the true value, so the correct option is (3).
