GCSE Geography

Geography asks learners to read and judge sources for bias, plan and evaluate a fieldwork enquiry, and write extended answers that reach a justified decision, all using precise geographical terms. Its numeracy is broad and applied: map scale, grid references and contours, sampling, averages and spread, percentage change, and drawing and interpreting graphs, all set out in Appendix B and used in every unit. The biggest thing Key Stage 3 should build is the habit of turning real local data into a correct graph and then a written conclusion that quotes the figures.

Skills that use Logical reasoning

  1. Averages and spread in fieldwork data

    Assessed: In the exam and in coursework (NEA)

    Learners process evidence using median, mean, range and mode, and at the top end quartiles, interquartile range and modal class, choosing the measure that best supports interpretation.

    Getting pupils ready

    Year 7
    Pupils record rainfall and temperature from a school rain gauge and thermometer for a week, then work out the mean and range.
    Year 8
    Pupils measure pebble sizes at five sites along a stream or beach and calculate the mean, median, mode and range, then say which average best represents each site.
    Year 9
    Pupils find the median and interquartile range of pedestrian counts from two parts of Aberdare, spot any outliers and use the figures to compare the sites.

    “Use appropriate measures of central tendency, spread and cumulative frequency.”
    Progression step 3
    • I can use mean to interpret a simple data set.

    • I can add and subtract numbers using whole numbers and decimals.

    Progression step 4
    • I can use mean, median, mode and range to compare data (continuous and discrete), and can choose the most appropriate average.

    • I can explore trends and extreme values (outliers) for data sets.

    • I can examine results critically, select and justify choice of statistics, recognising the limitations of any assumptions and their effect on the conclusions drawn.

    Progression step 5
    • I can interpret mathematical information; drawing inferences from graphs, diagrams and data, including discussion on limitations of data.

    • I can justify my procedures, predictions and conjectures.
