  To solve the problems in measuring coefficient of skewness related to extreme
value, irregular distance from the middle point and distance between two
consecutive numbers, "Rank skewness" a new measure of the coefficient of
skewness has been proposed in this paper. Comparing with other measures of the
coefficient of skewness, proposed measure of the coefficient of skewness
performs better specially for skewed distribution. An alternative of five point
summary boxplot, a four point summary graph has also been proposed which is
simpler than the traditional boxplot. It is based on all observation and give
better result than the five point summary.
