Descriptive Statistics for the data set a = [3,7,2,4,8,4,1,3] find the first three moments by direct calculation (not a calculator function), converting into standard deviation and skewness as appropriate. Compare the median to the mean, and explain what you see with reference to the skewness. What are the differences between the 50th percentile and the 25th or 75th percentiles? How does this relate to the question above?
