Determining Skewness In Ogive Graphs
I help you identify left skewness, right skewness, and bell curves in an Ogive graph. At 6:40 I said "this is left skewed"- that is incorrect. Skewness is determined by the direction of the tail. In the histogram, the tail tapers off to the right, so it is right skewed. Check out http://w

Assumptions: Spotting SKEWNESS in a Distribution (6-2)
Skewness is a measure of the imbalance or asymmetry of a data distribution. The skewness value can be positive, zero, negative, or undefined. Skewness can be caused when outliers exist on one end of a distribution and pull the mean toward the outlier. The skew is in the tail of the distrib

Kurtosis of a probability distribution (FRM T2-7)
[Here is my xls http://trtl.bz/121817-yt-kurtosis-xls] Kurtosis is the standardized fourth central moment and is a measure of tail density; e.g., heavy or fat-tails. Heavy-tailedness also tends to correspond to high peakedness. Excess kurtosis (aka, leptokurtosis) is given by (kurtosis-3).
