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 apply the method from video 1 to some messier data and verify that the plotted points cover more than half of the graph grid.
The data I use in this video comes from logarithmic calculations but you can still use the data for practice even if you are not familiar with log calculations since we are just fitting the numbers to the 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.
In the previous video ( • How to choose a scale ... ) I showed you the method applied. In this video I show the method applied 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.

Thank you very much Sir! I used this in my chemistry exam to find the scale for Arrhenius plot.

Hi how do you do this if you just have a full a4 sheet of graph paper

@PhysicsHQ 2 жыл бұрын

The method works regardless of the size of paper. The grid I used was in fact on that comes from A4 paper.

Hi sir thnks for the videos , I have a question. Is the divisible by 10 step a fix thing i.e we always need to find value which is divisible by 10 ?

Hi. Yes divisible by ten… because decimal system (e.g. there are ten small squares per large square on the grid).

This helped a lot but I do have one question. Do we always divide by just 14 and 10 or does it depend?

Hi. It depends on how many large grid squares you have on your grid. You might have a grid with 7 width and 10 length (large squares). In that case you would divide by 7 and 10 respectively.
