BUT WAIT! If you dig into this data, you'll find out that they only collected price points from couples who ACTUALLY PAID FOR THOSE PRODUCTS.
Problems with this data to discuss with your students:
1) No one who got stuff for free/traded for stuff would have their $0 counted towards the average. For example, one of my cousins is a tattoo artists and he traded tattoos for use of a drone for photos of their outdoor wedding.
2) AND...if you didn't USE a service, your $0 wasn't added to their ol' mean value. For example, we had our wedding and reception at the same location, so we spent $0 on a ceremony site.
3) As pointed out by Stephen Chew on Twitter, their is no measure of variability.
What does this mean? A website that sells All Things Wedding inflated the costs of weddings. Which is not great shock.
How to use in class:
a) A great example of bending the truth with actual data points.
b) An example of averages.
c) Why didn't they use median values?
c) If you are a social psychologists teaching stats, this example illustrates how data can be used to create a social norm ($33K wedding) and that norm can be used to exert pressure on people to spend more money at their wedding.
