A complete lesson covering the calculation of Chi square. It s designed fro specification point 6.1.2c of the OCR course but would be fine for any A level biology course.
It starts with a reminder of calculating mean and range before introducing the chi square. The lesson goes through the theory including critical values. It then moves on to a worked example.
The rest of the lesson is examples of the calculation including dihybrid inheritance. It also gives a reminder of using a punett square to solve a dihybrid problem. Most examples are based round genetics but one involving mitosis is included.
