Chapter 7 - Day 6
Students Struggled With…
Using appropriate notation for statistics and parameters of means and proportions.
Showing all required work for these probability problems. We look for very detailed work in these problems (pictures, formulas, work, and answer).
Remembering to check conditions for normality if not specifically asked to do so.
With every lesson, make sure to emphasize the correct symbols being used. Students will have tons of practice with these as the course goes on.
Whether its classwork or homework, have students reflecting on all the expectations we have had in normal distribution problems. Constantly holding these high expectations will have a huge payoff in inference.
Emphasize the importance of the conditions. Always refer to the picture at the top of Table A to constantly remind students that looking up a value on that table is only valid if we are on a normal distribution. If we want to use Table A and don't know the distribution is normal, we need to justify it is.
