3P.14—Unit 3 processing results

Process results by applying the correct calculation, units and significant figures before plotting or interpreting a relationship. The final mathematical pattern must still be biologically meaningful.

Choose a scale and graph type that match the variables, use a best-fit line only when appropriate, and check whether a calculated constant or relationship is consistent across the measured range.

A mitotic index is a proportion calculated from counted cells; a clear-zone area uses radius; a tensile experiment may compare breaking load while controlling fibre dimensions. Each output needs its own units and interpretation.

A straight-looking graph does not prove a linear law, and a constant derived from sparse data may be unstable. Show the calculation and state the range over which the relationship is supported.
