Reaction Time, including measures of variation
I modified the acitivities a bit to make it more challenging for my high school Statistics students. I l... (more)eft in the fun part of seeing the differences with or without sound, but I added some questions pertaining to variation: finding standard deviation, the C.V., and Chebyshev's intervals.
