- 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.

Graph grid I use is available for download: www.tes.com/te...
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.

thanks for the help this thing i had failed to understand graphing and calculating scales well
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 ☺️
You’re very welcome. All the best with your studies.
How 14 is divided and 10 divided?? Which rule is used?
@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.
And I went through that today 😢
THANK YOU SO MUCH. I ALWAYS STRUGGLED WITH PICKING SUITABLE SCALES. THIS HELPED SO MUCH. THANK YOU.
Amazing! I’m so happy that it helps. All the best with your studies.
Bro learn who to use lowercase
Will you be interested if I introduce to you a formula that can help you choose a scale for a graph?.
@@josephappiah2604yes
@@josephappiah2604 yes please!
Thank you so much! I struggled a lot when graphing manually especially selecting the right scales. This helped a bunch.
You're very welcome! Happy graphing from this day forward!
Compare to other teachers on this subject, you are one of the best.
Nice job.
Thanks so much! All the best with your studies.
THANK YOU SO MUCH!! I’ve been struggling with this for so long, and this helps with literally any data, bless you. Im so grateful for you, thank you so much 😭 ♥️
Amazing 🤩. So glad it helped. All the best with your studies.
This is a godsend, I could not find any useful videos on graphing, and then, came to your video, which helped immensely. Thank you very much!

Doing my IGCSE's currently...Thanks a lot for this video, It really helped!
All the best for your exams.
same :)
Good luck to you too!
@@PhysicsHQ Thank you! :))
@@PhysicsHQ THANKS ! the exam was soooo good !
Bravo ! You taught me more than my teacher did.
Boom! 💥
Well done for putting the effort in to learn something new. All the best with your studies.
You are an incredibly fantastic teacher! Great teaching approach.
Ah that’s brilliant. Thank you very much.

clear cut explanation and really helpful at that, thanks a lot
Thanks 🙏

Seriously, thank you so much. Your explanation regarding such topic was superb and helped me out to eliminate one of the major problems I always had to deal with, Truly appreciate it 🙌🏿🙌🏻👍🏿👍🏻

Amazing. Thanks for taking the time to feedback.

Why we multiply by 2 , this confused me
Me too why can’t 0.42 neatly divide?
The grid on the shirt was not a coincidence ...was it?
Of course not. That’s my graph day shirt 👔
This is going to use this to study for a test that is tomorrow!
All the best for the test!! 📝
Thank you so much and it has help me alot
Excellent explanation 👍🏻
Glad it was helpful!
Am so grateful for this video, am watching this right now 8:49 am in Nigeria.
You’re welcome. All the best.
I have a question? So does the minimum and maximum separation points of vertical and horizontal lines always have to be more than half of the grid? Is this just a general rule, because obviosuly I am not using 10 / 14 grid and in this case will I need to use half of what mine is? :)
This actually just changed my LIFE
thanks so much .😊😋
You’re very welcome ☺️
All the best with your studies - and exams!
Fantastic video, thanks a lot!
You are welcome!
Thank you, a real help
Great! All the best with your studies.
You video has really helped thanks
Brilliant! All the best with your studies.
thank you for the video!!! can I ask why do you use 2.5 for the y increments though? I thought the increments have to be 1 or 2 or 5 X10 to the power of n?
Hello good evening. Please i wish to know how to determine the scale of graphs because I face alot of difficulties with that. Thanks
Hi. Sure. If you need further clarification from any point in the video you can ask here.
@@PhysicsHQ ok thanks
Thank youuuuu so much ❤❤
Really helpful 😃
Thank you. Glad to hear it is helpful for you.
This is great 👍
Thanks so much! All the best.
Please can you make a video on how to find the error in a reading
Thanks from India ❤️
🇮🇳 🤩
You’re very welcome!
All the best.
sir, am not geting you clear, where did you get the denominator
14, why did you multiply by 2 .
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?
you are the best, may the lord bless for this video
Thanks so much 🙏
Every blessing to you too!
thanks
Thank you for r consultation
Thanks
love from INDIA ❤❤
You’re welcome ☺️
All the best
Thanks a Lot
I don't get how you got the scale, how were you able to decide to use 0 .5 and 2.5
the lower the number, the more spread out the values will be on the chart. If he used 0.42 scale, the max data point would be at excatly the 14th square. And he wants it to be divisible by ten because every big square has 10 little squares (1/10th), so it will be easier to chart (I think)
Hpw did 2.1 become 2.5 for each large square?
Hi. In choosing the scale of the y axis, why did you choose to use 2.5 specifically?
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.
@@PhysicsHQ Thank you
Hello. Please if using same example with x-axis = 4.59 as highest and -3.91 as lowest and y-xis= -4.60 as highest and -0.35 as lowest, what do we do??
Using a 10 by 10.
Nice 😊
Just Couldn't leave without a like and a sub
Thanks 🙏
All the best!!
🤩
Thankyou 😭 so muchh
Thanks sir 😮
You’re most welcome. 🙏
Thanks❤
You’re welcome.
why does this not work for me
what does neatly divisible by 10 mean
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.
I have eye problem I can't see is written on the board
Does not apply on a grapho n which there are 10 large boxes on horizontal axis.
Method applies to any size grid.
How did you get the 2.9/14 ??
2.9 is the difference between max and min data values. 14 is the number of grid squares.
Sir pls tell big square you have taken means 20 divisions?
The large square has 10 divisions.
What makes you decide to use 0.50 ?
It is a round number within my range. Round means neatly divisible by 2 , 5, 10.
where did the 14 come from in the first example...
ohh nvm its ayt thnxs this was very helpfull
It's the amount of squares
The grid is 14 × 10 large squares.
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?
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
Would you like to use formulas in choosing scales of decimal values
What do you mean by squares
A standard graph grid is made up of small (2 mm) grid squares. And those small squares are grouped in 10 × 10 large squares (surrounded by thicker grid lines). The large squares are what I was referring to.
Why are we using 14
The grid has 14 large squares along an axis.
Nix one👍
Interesting 😅😅
Where does 14 came from
14 large squares on the grid horizontally
Thanks @@Multisthetics
@ridhima1933 no problem
Cool
Thanks 🙏
I don't have understand 😭😪😪
what is the meaning of 0.50 this confuced me🥲
