Question

calculate karl pearsons coefficient of skewness for the following data on the number of red flowers on a plant 12,18,35,22,18​

Answer 1

Answer:

Step 1: Subtract the median from the mean: 70.5 – 80 = -9.5. Step 2: Divide by the standard deviation: -28.5 / 19.33 = -1.47. Caution: Pearson's first coefficient of skewness uses the mode. Therefore, if the mode is made up of too few pieces of data it won't be a stable measure of central tendency.
