10 graphs of experimental data are given. Can you use a spreadsheet to find algebraic graphs which match them closely, and thus discover the formulae most likely to govern the underlying processes?
When analysing scientific data, we often need to suggest a curve to fit a set of points, and deduce the equation of the curve.
In the interactivity below, you can access the results of a scientific experiment, but you can only access one measurement at a time, chosen at random by the computer.
By plotting the points you are given, can you sketch a curve representing the relationship between the two variables?
The data were recorded in three sets, A, B and C, beginning at three interesting points in the experiment, so you may wish to investigate each set separately. Alternatively, you can choose to investigate the combined datasets.
