Certificate in Business Data Analytics (CBDA) — Question 44

An analytics team is interested in reviewing the results of a public opinion poll that is going to be conducted at the end of the month. One of the factors the team is interested in, is ensuring the result set is statistically significant.
Why would this factor be important to the team?

Answer options

• A. Guarantee that the objectives of the poll are met
• B. Ensure that results are not biased or random
• C. Improve the likelihood of receiving a response rate of 100%
• D. To make sure the criteria for the target audience is met

Correct answer: B

Explanation

Statistical significance is crucial because it ensures that the results of the poll accurately represent the population, minimizing the chances of bias or randomness in the findings. While meeting poll objectives (A), achieving a high response rate (C), and targeting the correct audience (D) are important, they do not guarantee the reliability of the results like statistical significance does.
