(From Tiffin Year 7 scheme of work) (a) Recognise a variety of ways to display data: * Construct pie charts, and finding frequencies from angles (and vice versa). * Be able to construct and interpret bar charts. * Construct stem and leaf diagrams. * Understand frequency diagrams and how grouped data can be put in tabular form. Be able to construct frequency polygons. (b) Be able to analyse data and calculate statistics: * Calculate the mean, mode, median and range (not quartiles) from listed data. * Find the mean, mode, median, range from a stem and leaf diagram. * Calculate the mean from a frequency table and estimate a mean from a grouped frequency table. * Solve (non-algebraic) problems involving mean, including combined means. * Appreciate the difference between continuous and discrete data.
