Question

for the graphs below, for which probability distribution is the value of the median greater than the value of the mean? theoretical probability distributions negatively skewed normal (no skew) positively skewed frequency negativity direction perfectly symmetrical distribution positive direction negatively skewed normal, symmetrical distribution positively skewed distribution none of the above

Explanation:

In a negatively - skewed distribution, the tail is on the left - hand side. The mean is pulled in the direction of the tail. Since the median is less affected by extreme values, in a negatively skewed distribution, the median is greater than the mean. In a normal distribution, the mean = median = mode. In a positively skewed distribution, the mean is greater than the median.

Answer:

A. Negatively skewed
