Maths in A-level Biology (CIE A-level Biology)

Without doubt, the CIE A-level Biology specification contains a lot of maths calculations and every year, there are a large number of exam questions that require the application of a range of mathematical skills. Therefore, a clear understanding of how and when to apply these skills is closely related to success on this course and the following calculations are covered by the 7 lessons that are included in this bundle:

• Using the eyepiece graticule and stage micrometer to measure cells and be familiar with units
• Calculating actual sizes of specimens from drawings, photomicrographs and electron micrographs
• Using the chi-squared test to determine significance between the observed and expected results of a genetic cross
• Use the t-test to compare the variation of two populations
• Using the Hardy Weinberg principle to calculate allele, genotype and phenotype frequencies in populations
• Use Spearman’s rank correlation to analyse relationships between the distribution and abundance of species and abiotic or biotic factors
• Using Simpson’s index of diversity to calculate the biodiversity of a habitat

All of the lessons contain step by step guides that walk the students through the application of the formulae and there are lots of worked examples and exam-style questions for the students to use to assess understanding
