Mathematical skills include:
Calculate the mean, median, mode, range (e.g. height of group of organisms, number of stomata in a plant).
Determining the intercept and/or gradient using y = mx + c.
Calculating the rate of change from a graph with a linear relationship (e.g. rate of transpiration).
Drawing a tangent to a curve on a graph to calculate the rate of change (e.g. amount of product produced against time, at a fixed concentration of enzyme).
Calculate the standard deviation of a set of data.
