I need that ruler it’s so beautiful and will help you got an accurate gradient since it’s a range in the mark scheme sometimes I’m outside the range by like 10 or 12
Nice video! I have a question: if i am starting my y-axis from non-zero value (lets say frim 4) and my line of best fit is starting from the origin. In this case is my y-intercept 0 or 4 ?
Not really what i think you are looking for but the Amoeba Sisters is a great channel with easy to understand summaries for Olevel and Alevel biology. my teacher has used their videos multiple times to give us a good idea of what we are covering before moving on to the details.
So I had this graph where all the values are in decimals and all values are below 1 like 0.23, 0.26, 0.28, 0.30, 0.34, 0.36 what kind of a scale shall I select for these kinds of values?
I need to understand more on the rearrangement of the quantity related by the equation such that two variable are constant and determining it value after finding it gradient and y-intercept
+JBC Jackson You should draw the line of the best fit across the whole width of your x-axis. This means it extrapolates the line slightly but that is useful if you want to read off the y-intercept.
Ok really hoping you see this. My physics tutor doesn't let me start from any other number than 0 ever. E.g; if I start my y-axis from 60 because that's the first reading for the y-axis in my table, and then the x-axis goes from say 0-16, it's incorrect because what that's suggesting is that I have a reading for 0 when in fact I don't (if that makes sense). Similarly, the only time it's appropriate to start from non-zero values is when my axes start from the actual first values in my tables (e.g; 60 and 2). But this is so hard to do when we have numbers like 0.0053 and 914 as the first readings. He says to plot from zero even if my first reading is 914. And now I'm confused, especially since the mark scheme says to use over half the graph. Hope you get what I'm trying to say!
+Mel tansz Your graph axis only need to cover the points you plot. If you had y values of 60, 65, 70, 75, 80, 85 then you would start numbering your y-axis at 60 - otherwise all your data would be too squashed up at the top of the graph.

I am a physics teacher and your videos save my life
That’s great to hear that so many other teachers use them as well!
wow..this is really helpfull. thank you so much.I am a new subscriber to your channel..

Where can i get that ruler from?
Does it have to be from the first point to last
I think the small crosses or x's should not be used to represent the plotted points on the graph because of the error bars
I need that ruler, please tell us where you got it from T-T
You can buy the "line of best fit ruler" here: my.bestfitlineruler.com/
Really good channel. Do you have a channel you recommend for Chemistry and Biology. Many thanks
MaChem guy is great for Chemistry - I haven't seen one for Biology yet.

like 0.23, 0.26, 0.28, 0.30, 0.34, 0.36
what kind of a scale shall I select for these kinds of values?
a scale of 0.02 perhaps with the axis starting from 0.20
Your values should start from 0.20 then the value should have a difference of 0.02 like 0.22,0.24,0.26 and so on.
this is very important and i need it for tomorrow
can i go up in 15s
do the points have to be balanced? like, equal no. of points below and above the line?
Muhammad Siddiqui I believe so yes
GAYS ON ICE thanks dude....
Sometimes i dont start from zero at y-axis and the graph doesn’t match. What should i do
I need to understand more on the rearrangement of the quantity related by the equation such that two variable are constant and determining it value after finding it gradient and y-intercept
+Sanny Anthonio It depends on the equation you have. Which one do you need help with in-particular?
What kind of pens are those? They're beautiful

I dont really get where to start the line of best fit from..,. Is it from 0 or from where my data starts? Thanks sir

I can find the gradient even if doesn't start at 0?
which kind of ruler is this?
my.bestfitlineruler.com/
for a line of best fit with freehand what if it misses some points?? and thats the best ruler ever!
+Mohamed Maxamed As long as you give it your best attempt - and if you do it in pencil you can always rub it out and try again.
+A Level Physics Online thanks
Cant i have at least one point touching the line?
