for the graphs below, for which probability distribution is the value of the median greater than the value of the mean? theoretical probability distributions negativity skewed normal (no skew) positively skewed frequency x x x negativity direction perfectly symmetrical distribution positive direction negatively skewed normal, symmetrical distribution positively skewed distribution none of the above
Answer
Answer:
A. Negatively skewed
Explanation:
Step1: Recall property of normal distribution
In a normal (symmetrical) distribution, mean = median = mode.
Step2: Recall property of positively - skewed distribution
In a positively - skewed distribution, the tail is on the positive side. The mean is pulled in the direction of the tail, so mean > median.
Step3: Recall property of negatively - skewed distribution
In a negatively - skewed distribution, the tail is on the negative side. The mean is pulled in the direction of the tail, so median > mean.
