Graphs are drawn to show experimental data obtained during scientific experiments.
It is important to consider the following when drawing a graph:
Graphs are then used to identify trends present within the experimental data.
When forming a trend it is important to cover the entire graph.
Multiple trends in a graph should be individually described, using data as evidence.
As temperature increases from 0°C to 40°C, the time taken for starch digestion decreases.
As the temperature increases above 40°C, the time taken for starch digestion increases.
