Lesson details
Key learning points
- Possible outcomes for two events can be listed in a table.
- The outcome table can be used to generate a list of outcomes.
- A list of outcomes can be used to generate an outcome table.
Keywords
Outcome table - An outcome table is a table that shows all the possible outcomes.
Common misconception
Pupils may worry about which event/stage of the trial should be the rows and which should be the columns in an outcome table.
Explain that the rows and columns can be transposed. Depending on the context AB and BA may be the same outcome, whereas in other contexts they may be two different outcomes, so a little care is needed in interpretation.
You may wish to uses the multi-stage trial outcome table as a discussion piece to the lesson. It might be nice to make the pupils combine two different stages first, then compare the outcomes to the outcome table in the slide deck.
