Question: 32

2. In a sample of hospital patients, the mean age is found to be significantly lower than the median. Which of the following best describes this distribution?

  • A. Skewed right
  • B. Skewed left
  • C. Normal distribution
  • D. Bimodal distribution

Correct Answer: B

Explanation:

The mean is to the left of the median, which implies that the tail of the distribution is on the left side; therefore, this distribution is skewed left. It would be expected that there would be a low plateau on the left side of the distribution, which accounts for the shift in the mean.
