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? Use this free quiz: physicshq.wixsite.com/alevelp...
Graph grid I use is available for download: www.tes.com/teaching-resource...
In this video I show you the method applied. In the next video ( • How to choose a scale ... ) I apply the method to some messier data.
Relevant concepts: physics graphs, accurate graph work, picking a scale for axes, systematic values for graphs, maths skills in physics, maths for physics, maths hacks in physics.

This video is a life saver. I usually spend about 10 minutes trying to figure out the scale to use on my graph and i want to cry each time especially when my data is all in decimals.Thank you so much ☺️

How 14 is divided and 10 divided?? Which rule is used?

@PhysicsHQ 8 ай бұрын

@k_deep9583 hi. You have to count the number of large grid squares along each axis (vertical and horizontal) and then you divide the corresponding range by that number of squares.

Hi. In choosing the scale of the y axis, why did you choose to use 2.5 specifically?

@PhysicsHQ 2 жыл бұрын

Hi The scale has to be between 2.1-4.2 to use ~ half of the grid. The closer to 2.1 the better. 2.5 is neatly divisible from 10 (10/4 =2.5) so plotting will be easy.

Hi if using your same example of 14 by 10 what if for y axis the data starts at 3.9 and the biggest is 19.5 and for the x axis data it starts at 0 and the biggest is 9.7 how would you scale the graph by?

@PhysicsHQ 2 жыл бұрын

y axis: starts at 3.9 and the biggest is 19.5 (19.5 - 3.9) ÷ 10 = 1.56 (min scale) 1.56 × 2 = 3.12 (max scale) Round number between min and max ➝ 2.0 x axis: starts at 0 and the biggest is 9.7 9.7 ÷ 14 = 0.69 0.69 × 2 = 1.38 Round number between min and max ➝ 1.0

sir, am not geting you clear, where did you get the denominator 14, why did you multiply by 2 .

@PhysicsHQ 2 жыл бұрын

Hi. The 14 comes from the number of large squares across the horizontal direction of the grid. In my method I worked out a range for my acceptable scale: a minimum value which corresponds with using half the grid (7 large squares) and a maximum value which corresponds with using the entire grid (14 large squares). Does that make more sense?

what does neatly divisible by 10 mean

@PhysicsHQ Жыл бұрын

I mean by that not an awkward scale. For instance if we make 1 large square equal to 3 then a value of 1 will be at 3.3̇ on our scale. We typically consider that awkward. So avoid 1 large square to 3, 6, 7 and 9. Best to use 1, 2, 5 etc. 4 and 8 not ideal but ok.
