Instructional Ideas

• Lead a discussion on whether standard deviation is as meaningful with a skew distribution as a normal distribution
• Have the class generalize how to determine the direction of the skew based on the location of the median and mean

Classroom Considerations

• Individuals should understand the concept that data can be skewed or normal 

• This resource is only available on an unencrypted HTTP website.It should be fine for general use, but don’t use it to share any personally identifiable information

Pros
