Solve a problem by representing, extracting and interpreting data in tables, graphs, charts and diagrams, for example:

line graphs;

frequency tables and bar charts.

Core:

Calculate statistics for small sets of discrete data:

find the mode, median and range, and the modal class for grouped data;

calculate the mean, including from a simple frequency table, using a calculator for a larger number of items.

Interpret diagrams and graphs (including pie charts), and draw conclusions based on the shape of graphs and simple statistics for a single distribution.

Use vocabulary and ideas of probability, drawing on experience.

Understand and use the probability scale from 0 to 1; find and justify probabilities based on equally likely outcomes in simple contexts; identify all the possible mutually exclusive outcomes of a single event.

Collect data from a simple experiment and record in a frequency table; estimate probabilities based on this data.

Extension:

Recognise when it is appropriate to use the range, mean, median and mode; calculate a mean using an assumed mean.

Know that if the probability of an event occurring is p, then the probability of it not occurring is 1 – p; find and record all possible mutually exclusive outcomes for two successive events in a systematic way, using diagrams and tables.
