For a distribution, mean = 100, mode = 127 and SD = 60. Find the Pearson coefficient of skewness Skp.
The mean and variance of the distribution is 60 and 100 respectively. Find the mode and the median of the distribution if Skp = – 0.3.
For a data set, sum of upper and lower quartiles is 100, difference between upper and lower quartiles is 40 and median is 50. Find the coefficient of skewness.
For a data set with upper quartile equal to 55 and median equal to 42. If the distribution is symmetric, find the value of lower quartile.
Obtain the coefficient of skewness by formula and comment on nature of the distribution.
