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.
