Level 3 Hypothesis testing
Students carry out significance tests on proportions to test hypotheses about successful applicants to higher education.
Students learn about collecting data by stratified sampling and designing a questionnaire.
Students use relative frequency to estimate probability. They find theoretical probabilities including probabilities of combined events. They use probabilities to predict the expected number of trials in which an event will occur.
The addition law for probabilities of mutually exclusive events and the multiplication law for probabilities of independent events are introduced. Students then use these laws to tackle some probability problems.
Students use sunshine and rainfall data to carry out significance tests on the difference between sample means. They use a calculator or a spreadsheet to calculate mean and standard deviation values.
Students use a triangle test to decide whether or not people can tell the difference between a product and a healthier alternative.
