Distinguish Skewness And Dispersion. It measures the deviation of the given distribution of a random variable from a symmetric distribution such as normal distribution. Coefficient of skewness can be positive or negative.
With the help of skewness one can identify the shape of the distribution of data. Means Median or Mode. The difference between the mean and the mode adjusted for dispersion using the standard deviation of the distribution gives a good measure of skewness mean - mode standard deviation Because the distance between the mean and the mode in a moderately skewed distribution is three times the distance between the mean and the median the relationship can also be written as.
With the help of skewness one can identify the shape of the distribution of data.
DISPERSION In optics dispersion is. The tendency for the scores to gather around the middle of the bell curve. Skewness is asymmetry lack of equality between aspects of something in a statical distribution where the curve appears distorted skewed to the right or left side. Dispersion deals with the dispersal of the items of a series around its central value but skewness deals with the nature of distribution of a series ie.
