ASQ Certified Quality Engineer (CQE) — Question 72

Which of the following statements BEST describes a bimodal distribution?

Answer options

• A. This distribution shows stratified data and two distinct peaks.
• B. This distribution shows a single mode and bell shaped distribution.
• C. This distribution is truncated.
• D. This distribution has several distribution peaks.

Correct answer: A

Explanation

Option A is correct as a bimodal distribution is defined by having two separate peaks or modes. Option B is incorrect because it describes a unimodal distribution, which has only one peak. Option C does not accurately represent any specific distribution type, and option D refers to a multimodal distribution, which is not specific to bimodal cases.
