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

The mathematical element of the OCR A-level Biology A specification is substantial 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 9 lessons that are included in this bundle:

• Using the chi-squared test to determine significance between the observed and expected results of a genetic cross
• Using the Hardy Weinberg principle to calculate the frequency of an allele or a genotype in a population
• Calculating the standard deviation to measure the spread of data
• Using the Student’s t-test to compare the means of two sets of data
• Calculating the temperature coefficient
• Calculating the proportion of polymorphic gene loci
• Using and interpreting Simpson’s index of diversity to calculate the biodiversity of a habitat
• Using the Spearman’s rank correlation coefficient to consider the relationship of the data
• The use and manipulation of the magnification formula

A revision lesson is also included in this bundle which acts as a fun and engaging revision of the range of calculations
