You can measure skewness as the difference between the lengths of the upper quartile (Q3-Q2) and the lower quartile (Q2-Q1), normalized by the length of the interquartile range (Q3-Q1). This makes it easier to identify and calculate the various quartiles. You can use the following formula to calculate quartiles for grouped data: Q i = L + (C/F) * (iN/4 – M) where: L: The lower bound of the interval that contains the i th quartile; C: The class width; F: The frequency of the interval that contains the i th quartile; N: The Quartiles .
