• Processing and representing data
• Processing and representing data
• draw and produce, using paper and ICT, pie charts for categorical data, and diagrams for continuous data, including line graphs for time series, scatter graphs, frequency diagrams and stem-and-leaf diagrams
• calculate mean, range and median of small data sets with discrete then continuous data; identify the modal class for grouped data
• understand and use the probability scale
• understand and use estimates or measures of probability from theoretical models (including equally likely outcomes), or from relative frequency
• list all outcomes for single events, and for two successive events, in a systematic way
• identify different mutually exclusive outcomes and know that the sum of the probabilities of all these outcomes is 1.
• find the median for large data sets and calculate an estimate of the mean for large data sets with grouped data
• draw lines of best fit by eye, understanding what these represent
• use relevant statistical functions on a calculator or spreadsheet
• draw and produce, using paper and ICT, pie charts for categorical data, and diagrams for continuous data
• understand and use estimates or measures of probability from theoretical models, or from relative frequency
• find the median, quartiles and interquartile range for large data sets and calculate the mean for large data sets with grouped data
• calculate an appropriate moving average
• know when to add or multiply two probabilities (mutually exclusive events, independent events)
• use tree diagrams to represent outcomes of compound events, recognising when events are independent
