Educational Statistics

Central tendency, dispersion, correlation and the normal curve, as this paper asks them.

Educational Statistics

Statistics is the third leg of the Measurement & Evaluation block (~30% of the paper, ~90 of 300 marks, together with Chapters 1 and 2). The 2022 paper asked direct numericals — z-scores, coefficient of variation, skewness ordering, normal-curve percentages — and definitional items on central tendency and correlation.

The good news: the exam uses only friendly numbers. Every question is designed to be solved without a calculator in under 90 seconds — if you know which formula to reach for. This chapter teaches every formula from zero.
