Topic 22.3
22.3 Mathematical and data-presentation skills
Objectives in this topic
22.3.1 Numerical and algebraic calculations
- Add, subtract, multiply and divide; use decimals, fractions, ratios, reciprocals, percentages, percentage change and standard form; round to appropriate decimal places or significant figures; use direct and inverse proportion; solve simple equations and substitute quantities into formulas.
22.3.2 Geometry, measurement and biological scales
- Convert units including cm³ and dm³, mg, g and kg, and μm, mm, cm and m; use areas and volumes of common shapes, rulers, estimates, scale diagrams and surface-area-to-volume ratios; select appropriate units.
22.3.3 Graphs, charts and statistics
- Draw and interpret line graphs, bar charts, pie charts and equal-interval histograms; interpolate and extrapolate; determine gradients and intercepts with units; select scales and axes; recognise proportionality; calculate means and ranges; use simple probability.
22.3.4 Record readings and tabulated data
- Record readings to the precision of the instrument with correct units and significant figures; head table columns with quantity and unit separated by a solidus; omit units from table bodies.
22.3.5 Plot, analyse and present biological data
- Plot independent and dependent variables on correctly labelled axes using sensible scales; mark points accurately; draw justified best-fit lines or curves; read by interpolation or extrapolation; produce clear biological drawings and appropriate pie or bar charts.
