Importance of Repetition in Statistical Experiments

Subject : Social Studies

Question:

In statistical experiments, how many times should an experiment be repeated to achieve reliable results?

A. An experiment should be repeated as many times as necessary to achieve a statistically significant result and to ensure the reliability of the findings.

B. An experiment should be repeated only once to verify initial findings.

C. An experiment should be repeated a fixed number of times, regardless of the statistical outcome.

D. An experiment should be repeated continuously until the desired result is obtained.

Expert Verified Solution:

The correct answer is A. An experiment should be repeated as many times as necessary to achieve a statistically significant result and to ensure the reliability of the findings.

Explanation: This is because statistical experiments often involve random variables, and a single experiment might not provide enough data to draw reliable conclusions. Repeating the experiment multiple times allows researchers to account for variability, reduce the impact of outliers, and obtain results that are more likely to represent the true effect or relationship being studied.
