How to choose a scale on a graph | A-Level Physics How To

Got some data to plot on a graph and need to plot it onto a graph grid? What scale are you going to choose for your axes? In this video I demonstrate a method for choosing a scale so that the plotted points will consistenly cover more than half of the graph grid. Plotting points to cover more than half of the graph grid is an important part of doing accurate graph work (i.e. calculating gradients and intercepts). I hope you find the method easy to use and helpful in all your graph work. Want to check you've grasped the method?

In the next video (https://youtu.be/HKRtQhLU5A4) I apply the method to some messier data.
