The mean, median and mode of a set of data are related by the relation:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 3 Median − 2 Mean = Mode
For a moderately skewed distribution, Karl Pearson's empirical relation links the three measures of central tendency: the gap between the mean and the mode is about three times the gap between the mean and the median.
Mean − Mode = 3 (Mean − Median) = 3 Mean − 3 Median
Mode = 3 Median − 2 Mean
