How to Present Data - Line Graph.
There are a number of different ways of presenting data.
When both the independent variable and the dependent
are continuous, then the data is best shown as a line graph.
Below is a line graph showing
enzyme activity plotted against
temperature. Temperature is the independent variable.
The independent variable is always plotted on the X axis of a graph.
Note the increased number of
points plotted closer
between 35 and 45 °C where the graph changes shape (continued).
Other forms of data can be presented as a bar chart or a scattergram.
