Assessment

Learning Outcome 5: The learner will be able to collect, summarise, display and critically analyse data in order to draw conclusions and make predictions, and to interpret and determine chance variation.

Assessment Standard 5.9: We know this when the learner lists possible outcomes for simple experiments (including tossing a coin, rolling a die, and spinning a spinner);
