評価段階
A*ABCDEU
電卓の規定
A scientific or graphical calculator is permitted. Graphical calculators must be in exam mode with all stored programs and data cleared before the exam; the calculator must not be able to retrieve stored text or formulae.
過去問と採点基準にもとづいて作成（2024–2026）。
電卓プログラム
Graph: zeros, intersections & turning points
Graphical calculator / GDC (exam mode)
目的: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
使う場面: Checking solutions, sketching, or solving where an analytic method is hard.
手順
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Numerical equation solver
Graphical calculator / GDC (exam mode)
目的: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
使う場面: Iterative or implicit equations, or to confirm an algebraic solution.
手順
Use the equation/zero solver, entering the equation and a sensible starting estimate.
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Numerical integration & differentiation
Graphical calculator / GDC (exam mode)
目的: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
使う場面: Checking calculus answers, or where only a numerical value is needed.
手順
Use the GDC's numeric integral / derivative function with the limits or the point.
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Statistics & probability distributions
Graphical calculator / GDC (exam mode)
目的: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
使う場面: Statistics questions and hypothesis tests.
手順
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
試験での注意: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
よくあるミス
1high影響する配点: 4Application of Knowledge (AO2)
Presenting generic descriptions of concepts or studies in scenario questions (AO2) without linking back to the characters mentioned.
回避方法: Use the 'Scenario Anchor' technique: Ensure every theoretical claim is explicitly paired with a concrete detail from the text (e.g., using names like Ashvi, Jin, Antoni, or Stan, and referring specifically to their actions like playing football, using their phone, or failing to sleep).
2medium影響する配点: 2Quantitative and Statistical Analysis
Confusing Spearman's Rank critical tables with Wilcoxon Signed Ranks critical tables during statistical significance testing.
回避方法: Always verify the table title. Remember that for Wilcoxon, the calculated T value must be equal to or less than (<=) the critical value to be significant, whereas for Spearman and Chi-Squared, the calculated value must be equal to or exceed (>=) the critical value.
3high影響する配点: 2Wilcoxon Signed Ranks Test
Failing to exclude zero-difference scores in the Wilcoxon Signed Ranks test.
回避方法: If a participant condition score difference is exactly 0, do not rank that difference and subtract that participant entirely from your total 'N' sample size before looking up the critical value.
4medium影響する配点: 1Data Analysis Skills
Leaving ratios unsimplified or rounding values mid-calculation, compounding rounding errors.
回避方法: Express ratios in their lowest possible simplified whole-number form (e.g. 12:2 should be 6:1). Keep precise decimals throughout your calculation steps, and round only at the final result to the decimal criteria specified (e.g., two decimal places).
Confusing statistical infrequency with failure to function adequately when defining abnormality.
回避方法: Remember that statistical infrequency is strictly numerical (evaluating the mathematical rarity of a behavior in a population curve), while failure to function adequately focuses on whether an individual can cope with the demands of everyday life (using criteria like Rosenhan & Seligman's criteria, such as unpredictability or maladaptiveness).
