In a negatively skewed distribution, which among the following would be true? Choose the correct answer from the options given below.
- 1. Mean is greater than Mode
- 2. Mean is less than Median
- 3. Median is less than Mode
- 4. Mode is greater than Mean
A1 and 2 only
B2 and 3 only ✓ Correct
C2 and 4 only
D1 and 4 only
Correct answer: (B) 2 and 3 only — In a negatively skewed distribution the mean is less than the median and the median is less than the mode, so the answer is 2 and 3.
Explanation
★In a negatively skewed distribution the mean is less than the median and the median is less than the mode, so the answer is 2 and 3.
★Negative skew has a longer tail on the left side of the distribution.
★The extreme low values pull the mean down below the median.
★So the mean is the smallest of the three central measures.
★The order becomes mean less than median less than mode.
★So mean below median and median below mode both hold, which is statements 2 and 3.
