P3.4—Recording data and observations

Tables should distinguish raw from processed data, use descriptive headings and put units in headings rather than repeating them in cells.

Place the independent variable before the dependent variable and use justified decimal places.

A table headed “temperature / °C” and “rate / cm³ min⁻¹” lets a reader interpret every entry without guessing units.

Do not round raw readings prematurely or hide important variation in a single mean.
