P3.4—Recording data and observations

A results table keeps raw readings and observations together with a heading, quantity and unit for every numerical column. Record zeros or no change explicitly when they are meaningful.

Use consistent decimal places supported by the apparatus and do not round raw readings before calculations. Separate qualitative observations from inferred explanations.

A titration table can show run number, initial burette reading / cm³, final reading / cm³ and titre / cm³; “no precipitate” is a valid observation, not a blank cell.

A table is not a place to hide calculated averages in place of raw readings, and units should not be omitted from headings.
