You don’t have a cat? Then why not reading the Stats With Cats blog written by Charlie Kufs. He writes about various subjects such as correlation, modelling, fixing data issues and any topic related to statistics.
He recently wrote an excellent post entitled Ten Fatal Flaws in Data Analysis. He explains common issues when dealing with statistics. He writes about issues wuch as sampling, variance and testing for example. Here is my favorite sentence from his post:
“Just as correlation doesn’t necessarily imply causation, significance doesn’t
necessarily imply meaningfulness.”
