Objectives:


Support:

  • 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.

Key Vocabulary:

  • mean, median, mode, range, modal group, frequency, tally, average, discrete, certain, likely, unlikely, impossible, chance, likelihood.
