Students Struggled With…
Using correct notation when identifying parameters and statistics.
Using a sampling distribution to make decisions about claims.
Sometimes, students just have to get something wrong to learn. We told students before the quiz that they should study the notation, but many students still used p when they should have used μ. And that’s ok, they will probably remember this for longer now.
Using a dotplot to make a decision about a claim is a precursor to significance tests. Often an assumption is made and a simulation is conducted. It’s very important that students understand what the simulation is modeling in order to interpret their result properly.
