Topic Area 2: Handling scientific data

2.4.1 Identifying patterns and
relationships to:
Draw conclusions
Accept or reject a hypothesis
Inform further scientific investigation

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.
