WebAnalysis of Quantitative Data 72 E2) For a frequency distribution the Bowley’s coefficient of skewness is 1.2. If the sum of the 1st and 3rd quarterlies is 200 and median is 76, find the value of third quartile. E3) The following are the marks of 150 students in an examination. Calculate Karl Pearson’s coefficient of skewness. Karl Pearson developed two methods to find skewness in a sample. 1. Pearson’s Coefficient of Skewness #1 uses the mode. The formula is: Where = the mean, Mo = the mode and s = the standard deviation for the sample. See: Pearson Mode Skewness. 2. Pearson’s Coefficient of Skewness #2 uses the … See more In general: 1. The direction of skewness is given by the sign. 2. The coefficient compares the sample distribution with a normal distribution. … See more There isn’t an Excel function to find Pearson’s coefficient of skewness.
