Support (from Y7 teaching programme)
• Calculate statistics for small sets of discrete data: find the mode, median and range; calculate the mean, including from a simple frequency table, using a calculator for a larger number of items.
• Construct, on paper and using ICT, graphs and diagrams to represent data, including bar-line graphs; use ICT to generate pie charts. |
Core (from Y8 teaching programme)
• Calculate statistics, including with a calculator; recognise when it is appropriate to use the range, mean, median and mode and, for grouped data, the modal class; calculate a mean using an assumed mean;
• Construct and use stem-and-leaf diagrams.
• Construct, on paper and using ICT:
- pie charts for categorical data;
- bar charts and frequency diagrams for discrete and continuous data;
- simple line graphs for time series;
- simple scatter graphs ; identify which are most useful in the context of the problem .
• Interpret tables, graphs & diagrams for both discrete & continuous data, & draw inferences that relate to the problem being discussed; relate summarised data to the questions being explored. |

GCSE assessment criteria
|
What is an appropriate graph / chart for this? Why?
Can the mean = median = mode?
What do the scales mean?
Where has the data come from?
Is it more efficient to use ICT here?
Are scatter diagrams appropriate for these data?
What does the graph tell you?
Why would you choose to use ICT here?
What is wrong with this graph/chart?
Why is this graph misleading?
Does this piece of data fit the trend. If not, can you think of a reason why it doesn't?
