The four key points are discussed when describing distributions in statistics...Shape, Center, Spread, and Outliers. Please forgive the misspelling of DESCRIBED in the video.
TIP to identify Left & Right Skewness: (Thanks LeBadman:)
Left: Mean is less than Median is less than Mode
Symmetrical: Mean, Median and Mode are approximately equal
Right: Mean is greater than Median is greater than Mode
You just take: Mean, Median, Mode
If it's left skewed, you will see the inequalities pointing to the left.
If it's right skewed, you will see the inequalities pointing to the right.
