Graphical interpretation

6. Plenary

Required Resources

• Slide 17

Delivery

• Invite students to consider other situations in which previous activity can be an indication of future performance or outcome (e.g. sports prowess, financial markets, crop production) and the associated professionals that gather and use this data for predictive purposes.
• You may want to invite students to come into your 'betting shop' and to suggest subjects on which they would like to place a bet. In response to this, some students may volunteer subjects on which it is less easy to place reliable odds, due to there being no precedent against which to forecast (e.g. the date of the next Royal Wedding), contrasting clearly with those events prompted by a direct relationship between specific variables.

Differentiation

Lower Ability:

You may wish to use the plenary for a more formal revision of the key insights into graphical interpretation, specifically the difference between linear and non-linear graphs. Students should be able to provide examples of each graph type unprompted.
Slide 1 may support less able students' consideration of other situations where previous activity can assist in forecasting future performance or outcome.
