<p>Precisely matched to Edexcel’s exam-accompanying formula and critical values table, this 8-slide PowerPoint gives a conceptual explanation of the Mann-Whitney U and a step-by-step worked example. The worked example uses a typical exam scenario and clearly shows what to substitute into Edexcel’s Mann-Whitney U formula. The formula is then calculated and the associated reading is taken from Edexcel’s critical values table and interpreted in the context of the question. The worked example is followed by a very similar task (with revealable answers) for students to try.</p>
