When P-0 the data are symmetric. Calculate the coefficient of skewness for each distribution. Describe the shape of each. (a) The coefficient of skewness for x-17, s-21, median = 19 is P- (Round to the nearest hundredth as needed.) Enter your answer in the answer box and then click Check Answer 3 parts remaining
Explanation / Answer
A) P = 3(17-19)/2.1 = -2.857
As the coefficient is less than 0, the distribution is skewed left.
