A how-to guide for the A-level Biology Hardy-Weinberg calculations. Includes worked examples

OCR A-Level Biology Statistical Tests Mindmaps. The download includes mind maps covering all statistical tests, such as the Chi-Squared Test, Hardy-Weinberg Principle, Standard Deviation, Student's t-test and Spearman's Rank. These mindmaps fully align with the OCR Specification. Digitally produced using multiple sources such as the specification itself, a variety of videos and recommended revision guides, as well as the use of the OCR Exam Mark Schemes and previous questions to ensure the resource is fully equipped with the information needed for taking an exam. I created this resource for my own revision and achieved an A in my A level exams in 2023.

University - STANDARD DEVIATION (SD) Standard deviation measures how spread out the data are around the mean (average). It shows the typical distance of observations from the mean. WHAT SD TELLS US: • Small SD → values are close to the mean. • Large SD → values are widely dispersed. • SD = 0 → all observations are identical. • SD is expressed in the same units as the original data. • SD alone does NOT tell you whether data are normally distributed. EXAMPLE: Two groups can have the same mean but different SDs. Group A: Mean = 70, SD = 3.2 → values are close to 70. Group B: Mean = 70, SD = 12.8 → values are more widely spread. COMMON MISCONCEPTIONS: ❌ SD is not the same as the mean. ❌ A larger SD does not mean the mean is larger. ❌ SD does not tell you the shape of the distribution. ❌ SD is not the same as variance. Variance = SD² TAKEAWAY: Standard deviation tells you how much the data vary or spread around the mean. It is a key measure of variability in research and data analysis. | Facebook
