HOW TO CALCULATE SLOPE AND ERROR IN SLOPE

This video talks about tips on how to calculate slope and error in slope using the range method. W represent width, n represent the number of observation and R represent the horizontal range.

[@EneOche-sj7zo]

Thank you Sir for this

[@zerokiller4329]

This was very helpful I understood at once

[@athsocial]

Thanks for the explanation

[@ebubesunday4880]

Thank you sir

[@amubieyaayomide6961]

Wow you are very good sir

[@vibey12]

May Allah reward you and enable your knowledge to reach larger audience

[@smartedutv]

Amin thanks

[@victorywilliam4316]

Really helpful 😊

[@ovikscollection2662]

Me as A 200l University student I just understood this now God bless you sir very easy with you❤

[@lomekamaineapa]

Thank you so much this really helped in my report.

[@ayowizz.507]

Sir I'm so grateful as an 100lv student this really helped me remember 🙏🙏🙏

[@vibey12]

Are you in fountain

[@emmanuelonyeri7074]

The video explained a lot
Thank you

[@user-nz4ri4qt6p]

this was very helpful for my physics practical

[@smartedutv]

Good... please share!!!

[@ritaese]

Thank u sir

[@user-il4ir2ut8d]

Thanks sir😊❤

[@abimbola2428]

Thanks for the video, sir. It simplified the standard error calculation.
But can we use ohms as the unit instead of V/A?

[@RajanikantaDas-bf4rx]

Love from India 🇮🇳 ❤❤❤.
Thanks you sir ❤

[@smartedutv]

Thanks... Pls share with friends

[@user-gz1le2hs3c]

Thank very much

[@OgbonnaChibuchi]

sir thank you but the formula is it for only voltage and ampre

[@smartedutv]

Yes according to the slope

[@Campus_lifestyle]

W=vertical scatter and points farther away are what should be used

[@abimbola2428]

Can we just use ohms as the unit rather than V/A?

[@smartedutv]

Sure...it's the same as ohms

[@user-dp5qh3lm3y]

Thank you for the tutor but I'm a little bit confused how you got the 2.5 in the ending

[@smartedutv]

It's just the same method of calculating slope.

[@TochukwuAnunobi]

What if all the points connect together

[@smartedutv]

Not possible in real experimental physics. You are trying to say your work is 100% accurate. The most accurate engine is Carnot engine which is not 100% efficient. That's why when we calculate efficiency in physics, the result is always less than 1

[@user-yh5tf5hc4s]

What if u have only one point

[@smartedutv]

You should have at least 2points on the line of best fit

[@Hobovai]

What if there are three points that do not fit

[@smartedutv]

You mean three points that do not fall on the best fit....in that case we choose the points closest to the best fit to calculate the error in slope

[@user-fw4ll8jy5b]

What if the broken lines are on one side only how do u get w?

[@danielstones1150]

Omo why dis guy Dey shout like dis 💔😂

[@orumahwisdom4469]

I taught you are not supposed to take the slope from the ploted point

[@smartedutv]

You can take your slope from any part of the line of best fit. Always ensure the triangle is reasonably big.

[@ChimezieJonah]

I thought w is calculated with the farthest scattered point 🥲. Also, I'm still confused if ruler can be used to measure w and R instead of subtracting 😢

[@smartedutv]

Yes of course...we pick the farthest point apart....

[@ChimezieJonah]

@@smartedutv , but you said the one closer to the line of best fit should be used 😫

[@farukmuyideen3307]

​@@ChimezieJonahit's the closest you'll use

[@Campus_lifestyle]

Yes you are right...that is a mistake to be corrected.
W is vertical scatter so it should be vertically written.

[@Campus_lifestyle]

Yes
