IB Maths AI SL Hypothesis Testing – Unit 10: chi-squared tests, t-test, p-values, IB-style test

A complete, ready-to-teach unit for IB DP Mathematics: Applications and Interpretation SL, Topic 4 (SL 4.11). Three animated lessons: the unit covers hypotheses, significance levels and p-values, the chi-squared test for independence, the chi-squared goodness of fit test and the two-sample t-test. An IB-style unit test then checks what students have learned. The same content is in the AI HL core, so it works for HL classes too.
Animated slides that teach step by step
Every question appears first. Each click fades in the next line of working or the next answer, so you can ask students to predict the next step before you reveal it. A PDF copy of each deck shows every answer: ideal for cover lessons, revision and absent students.
What’s included
• 3 lessons (39 slides): The Chi-Squared Test for Independence; The Chi-Squared Goodness of Fit Test; The t-Test
• Each lesson: starter, key ideas (formula booklet references), 4 worked examples with GDC steps, ‘your turn’ questions, an exam-style question with an IB-style markscheme, an exit ticket and a summary
