Mr Junior, 🖐 I have to say that u are a great teacher, you know that right, 👍 u have helped me alot, you explain it really Good, I understand it alot better now than what my teacher have Teached me
Thank you sir, my question is this . When you have the starting point (0,0) , can you draw the best fit line without starting to the orgin ?? Please explain me clearly
Yes you can draw the best fit line without it passing through the origin (0,0). If the data values have a point the correspond to (0,0) the best fit line will pass through the origin but generally once you have accurately plots all your points based on the trend you can determine if the best fit line should pass through the origin
Good day Sir looking at data point 3 and data point 4 can measure the distance in millimeter from the data point to the best fit line and then declare these distances are so close that the data point above the lines' distance is the same as the data point below the line??? your comment(s) is eagerly awaited. thx Ibrahim (all the way from South Africa)
Can you start a graph not from 0 . For example if you have really large numbers on x - axis can you start from 30 and go from there or should you always start from 0.
@@realJuniorRoberts one more question , the scale that we choose for our graph for example 1:1 , does it need to be the same for x axis and for y - axis , or could we us a scale of 1:5 on the x - axis and 1:1 on the y - axis
@@aleshamalcom2200 also when you plot a velocity time graph or displacement time graph you will simple connect the points as seen here ua-cam.com/video/Q3rZ0IRvVSk/v-deo.html

How do you determine the extension value which is not correct
@@kevinmphoclintbojelo4698 I'm not sure I understand your question
Thanks Sir…after watching this vid I feel like my teacher wasn’t teaching at all…I learnt a lot…new subscriber added!
Thank you for watching. I'm glad you found this video helpful 👍🏾
Blasting your teacher is not a very good thing to do. We know how you 21st century learners operate
Whose here in 2022 and this is still very helpful.
Thank you so much mr roberts,this helped me from c's in graphs to a's.
You're welcome. I'm glad to hear you've been improving in physics. Keep up the good work 👍🏾👍🏾
Explained in a delicate yet detailed manner, besttttt!
Thank you for watching 👍🏾

Really helpful thank you Sir.
Thank you for watching. Glad you found this helpful 👍🏾
Same
Sir I could not understand a thing my teacher said but you sir..thank you I have my exam soon and this helps
This is a great video for students.
Thanks sir you are doing a great job I have understood everything now 😍❤️
You're welcome. All the best in your studies

Yes that's correct. That's what we expect to obtain once we have drawn what's considered the best fit line. Thank you for watching 🙏🏾
Can you start a graph not from 0 . For example if you have really large numbers on x - axis can you start from 30 and go from there or should you always start from 0.
You can break the graph if the smallest value is significantly larger than 0
What are the values you are plotting?
@@realJuniorRoberts I am plotting values between 30 and 60 on the x axis and values between 0.1 and 3 on the y axis
@@zake726 okay you can break the x axis and start close the 30 on the x axis
@@realJuniorRoberts one more question , the scale that we choose for our graph for example 1:1 , does it need to be the same for x axis and for y - axis , or could we us a scale of 1:5 on the x - axis and 1:1 on the y - axis
Nice teaching sir 😁
Thanks for watching
Thank you sir! I had the misconception about the origin
You're welcome. Thank you for watching. I'm happy this video was helpful
In terms of best fit line does it have to pass through as many points as possible?
Yes you would want the best fit line to pass through as many points as possible showing an even distribution about the line
The video is nice and easy to understand
Thanks for watching. I'm glad you found this helpful
The lines must always be straight??
Thank you this video was really helpful🙏🏽.
Some graphs may require a curve such as the graph for radioactivity

Very helpful....thank you sire!
Thanks for watching 👍🏾
Thank you so much sir❤
You're welcome
Glad you found this video helpful
5:13 is it up to us to choose the scale ratio?
Yes you will choose the scale that best suits the data set you have. Do you have a range of values you wish to create a scale for?
Thanks very much sir cos am having physical exam tommorow
Thanks for watching. Glad you found this video helpful 👍🏾
wow nice job
wow sir got a youtube channel with 2 k 😲
🙏🏾🙏🏾
Its okay sir😊😊
👍🏾🔥🔥
Lovely
💯💯😄😄😄😁
Thanks for watching Shernice 👍🏾
Does the best fit line not have to start at the origin (0)?
No it doesn't have to start at the origin. The objective is to get a line showing the average of all points
@@realJuniorRoberts oh okay. Thank you!!
@@angie.44 you're welcome. Thanks for watching 👍🏾
sir im having problems with the latest assignment u gave me
What problem you having specifically?
@@realJuniorRoberts oh sorry i was rewatching the recording for last class when u sent this
@@realJuniorRoberts im having a problem finding out the distance of which im to separate the scale and identifying what the gradient is
@@realJuniorRoberts this is dorma sir do you have a number i can contact?
