Calculations, Graphs and Data Evaluation
Calculate accurately, interpret patterns and anomalies, and evaluate conclusions through validity, reliability and limitations.
How to prepare for the written examination
Move from accurate theory to a scenario-specific mechanism, consequence, evidence and judgement. Complete all practical performance and NEA work only through authorised centre arrangements.
Core concepts
Concept 1
A calculation needs the correct formula or operation, substituted values, units and sensible rounding.
Exam cue: Use the formula or numerical convention supplied or required by the current board.
Concept 2
Data analysis identifies pattern, magnitude, comparison and anomaly rather than merely repeating values.
Exam cue: Show working and interpret the result in the sporting context.
Concept 3
Evaluation judges whether design, measurement, sample and alternative explanations justify the conclusion.
Exam cue: Name a material limitation and explain its effect on confidence or generalisation.
Risk pitfalls and guardrails
Giving a number with no unit or contextual meaning.
Guardrail: Do not replace explanation with a named sport, an undated current example or practical work that belongs to NEA.
Ignoring scale or axis breaks in a graph.
Guardrail: Do not replace explanation with a named sport, an undated current example or practical work that belongs to NEA.
Listing limitations without explaining their consequence.
Guardrail: Do not replace explanation with a named sport, an undated current example or practical work that belongs to NEA.
Memory anchors
Calculation chain
Formula, substitution, working, result, unit and interpretation.
Data anomaly
A result that does not follow the main pattern and needs investigation.
Data validity
How well the evidence measures or tests the intended claim.
Data reliability
How consistently the method or measure would produce comparable results.
Data-limitation consequence
Explain how a weakness changes confidence, comparison or generalisation.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
