Day 81: Population, Sample, Sampling Distribution, Oh My!
The whole idea of a Sampling Distribution is mind-blowing for first time statistics students. Part of the problem is vocabulary, part is the notation, and part is the concept of the mean of the means or mean of the proportions. Lots of layers of complexity.
I must say that the Rice University applet on Sampling Distributions is just awesome! I’ve used this applet for years now and I have not found a more versatile, yet easily accessible, visual. Students get a concrete, visual introduction to the concepts surrounding the building of a sampling distribution…and it works now on our iPads. Yay!! Give it a try…I think you’ll fall in love with it, too. What visual aids do you use in the classroom to help students get a mental picture?
