P5.4-Tables, graphs and uncertainty treatment

Complete tables using Paper 3 conventions, calculate and record derived quantities, plot graphs with error bars, draw best-fit and worst acceptable lines, and calculate uncertainties in derived quantities, gradients and intercepts.

Use tables, graphs and uncertainty treatment to connect the rule to the data and decision in the question.

This matters because tables, graphs and uncertainty treatment determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply tables, graphs and uncertainty treatment to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Tables, graphs and uncertainty treatment is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
