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. |
Calculate statistics for sets of discrete and continuous data, including with a calculator and spreadsheet; recognise when it is appropriate to use the range, mean, median and mode and, for grouped data, the modal class. |
Calculate statistics and select those most appropriate to the problem or which address the questions posed. |
Use an appropriate range of statistical methods to explore and summarise data; including estimating and finding the mean, median, quartiles and interquartile range for large data sets (by calculation or using a cumulative frequency diagram). |
Use an appropriate range of statistical methods to explore and summarise data; including calculating an appropriate moving average for a time series. |

Construct, on paper and using ICT, graphs and diagrams to represent data, including:
• bar-line graphs
• frequency diagrams for grouped discrete data
• simple pie charts. |
Construct graphical representations, on paper and using ICT, and identify which are most useful in the context of the problem. Include:
• pie charts for categorical data
• bar charts and frequency diagrams for discrete and continuous data
• simple line graphs for time series
• simple scatter graphs
• stem-and-leaf. diagrams
