Four-Step Practice for Significance Tests
Chapter 9 - Day 9
Learning Targets
-
Use the four-step process to perform a significance test about a population population.
-
Use the four-step process to perform a significance test about a population mean.
Chapter 9 Study Sheet
This one-page document will allow students to put all the important formulas and conditions from Chapter 9 all into one place. Once completed, consider asking the following two questions:
"What is the same for proportions and means?"
-
Random condition
-
General formula
-
one-sample
"What is different for proportions and means?"
-
notation
-
Large Counts vs. Normal/Large Sample condtition
-
z tests statistic vs. t test statistic
-
Specific formula
-
Name of the procedures
-
How to find P-value
Four-Step Whiteboard Critique
This is a teaching strategy that we will use several times during the next few chapters. Here is how it works:
-
Assign students a 4-step problem to work on in pairs.
-
Monitor the room to support student learning. As each pair finishes, send them to the white board to write up 1 of the steps STATE, PLAN, DO, or CONCLUDE. The first two pairs should handle the PLAN and the DO because they take the longest to write up.
-
Once all 4 steps are on the board, call the class back together as a group. Ask them to critique the solution on the board as if it were a quiz or test question. Make any revisions with a red marker. This is your opportunity to make clear your expectations for a 4-step problem on an assessment.
