You need to know some maths for A level Biology. This includes knowing how to interpret averages (mean, median and mode), ranges, and standard deviations to work out whether an experiment can be said to have shown an effect or not. Master this early on and it will not help you with exam questions, but also make it easier for you to learn the bits of the course that are explained using these statistical methods.

Example 2: Q3 Paper 2 2023

This next question is more complex, and there are two ‘suggest’ questions.

But first - I always recommend you don’t read the actual questions until you’ve looked at the background information, graph etc. Doing this will help you avoid getting overwhelmed and jumping to mistaken conclusions (which is very common in exam situations!).

So let’s keep the questions for later. First make sense of this:

OCR A Level Biology: Mastering Biodiversity and Simpson's Index (Section 4.2.1 a-d)

Prior Knowledge to Recap

Before diving into biodiversity questions, ensure you understand these foundational concepts:

• The three levels of biodiversity: genetic diversity (variation within species), species diversity (number and abundance of species), and habitat/ecosystem diversity (range of different habitats)

• Species richness vs species evenness: richness is the total number of different species present, whilst evenness refers to how similar the abundance of each species is
