Sort, represent and interpret category data
Learners sort and organise category data and represent it on graphs. |
Sort, represent and interpret category data
Learners sort and organise category data and represent it on graphs. |
Sort, represent and interpret category data
Learners sort and organise category data and represent it on graphs. |
Understanding chance
Learners develop their concept of chance by discussing the likelihood of different events and use fractions to assign likelihoods to outcomes. |

Sort, represent and interpret number data
Learners sort and organise number data and represent it on graphs. |
Sort, represent and interpret number data
Learners sort and organise number data and represent it on graphs. |
Sort, represent and interpret number data
Learners sort and organise number data and represent it on graphs. |
Theoretical probability
Learners develop their understanding of the difference between theoretical and experimental probabilities.
Using frequencies to predict
Learners use the frequencies of outcomes to predict the likelihood that an event will occur, and learn that probabilities are not absolute predictors in the short run. |

Sample sizes
Learners develop an understanding of how sample size influences the accuracy of a survey.
Understanding the mean 1
Learners develop an understanding of the concept of a mean as a number that represents what all the data items would be if they were levelled out to be the same.
Understanding the mean 2
Learners develop an understanding of the concept of the mean as the ‘balance point’ of a set of data. |
Understanding media reports that include statistical information
Learners develop the ability to interpret and critically analyse a media report that includes statistical information. |
Fair games?
Learners explore issues related to gambling to further develop their concept of chance and to develop an understanding of expected value.
Lotto winners
Learners learn to use tree diagrams, organised lists and how to multiply probabilities to calculate the theoretical probability of winning Lotto. |
