PSLE-SCI-REALITY-0157. A Primary 5/6 guide to “100% inspected” quality claims: why checking every unit does not guarantee every defect was detected, and why method capability still matters.

PSLE Science Reality Lab Vol No.156 | “R² = 0.90” — Does That Mean 90% of the Predictions Were Correct?
PSLE-SCI-REALITY-0156. A Primary 5/6 guide to R² in scientific reports: why R² = 0.90 does not mean 90% of predictions are correct, and why residuals, validation and range still matter.
