Some of my AP Stats learners figured out why I have been high fiving them every time they enter my room. I showed some videos about the placebo effect today, and a couple at the end of class commented on the fact that the high five is kind of like a placebo, because high fives are given for great things, and I do it on entering so it changes their mindset.
They got me. I hope they don’t spread that around, it would start ruining all my tricks.
Nothing spectacular today in class, just finishing some notes on experimental design, blocking, placebo effect and lurking variables. In Alg 2, I gave them a quiz that had them really thinking. They had to graph the 8 parent functions, and then also tell me which ones had all positive y values. Which ones were always increasing, or had a vertex at (0,0).
Some had only one answer, some had 6 or 7 answers, so they had to really think about the words and connect the meanings with the big picture of each parent function.
Great thinking type of quiz. I am excited to grade them.
Finally, you know all those AP learners in Stats who ask, “Well, what if it is not normal?” or “why are we assuming that, couldn’t it be wrong?” Yea, I love the too. I learned the answer today in my Non-Parametric Statistics class. You handle them by doing non-parametric tests on them instead of parametric tests (t test, z test, etc).
DOH! Of course. I am excited by this class. Lots of great extension to the Stats content while not being too much work. Unlike the Qualitative Statistics course. That is going to be a ton of work. Oh well, I signed up for it knowing it would not be all fun and games. No reason to complain now.
