Sir I have a question~ sir while calculating percentage error why we did not take the round off value .Please explain if we take the round off value then we get 2% inspite of 1.5% .please explain.plzzzzzzzzzzzzzzz. 15:05 (video duration)

[@yogeshwarsingh7975]

same question i also have... if u get answer can you please share?

[@Niksoyam]

because while calculating the percentage error we are supposed to take the exact relative error not the round off value

[@vikasgautam7392]

Percentage error 1.5 is correct answer not not 2% becouse in relative error round off value is 1 after decimal and in % error also have 1 round off value after decimal ( Agar answer tumhe sahi lagta h to like karo)👍

[@revengegameryt9979]

Answers 2% hoga not 1.5%because in previous lecture in topic multiplication and division we see small significant and 100 convert in 1 significant so it is small and answers will be in 1 significant there is 2 %

[@ValowithAman]

That's 1.5 not 15%

Very good teaching sir,

[@DineshSingh-dp1tx]

Sir our doubt is why we take relative error is 0.015 not 0.02

[@Bkprahar]

You can take any of 0.02or 0.015 but as we can get exact value from 0.015 so we can take that only

[@khanazaan10khan76]

Yes also mine dear

[@Aditisri00]

Yes, same doubt why we take 0.015 while finding percentage error not 0.02

[@_tanya_24]

@@Aditisri00 we take the exact value of relative error to find %error 👍

[@_tanya_24]

So we take 0.015 instead of 0.02

[@deveshbajpai9699]

Sir in ncert, absolute error is given as actual measurement - mean value ...

Sir to calculate relative error we took the round off value of delta Xm so to calculate %error why can't we take the round off value

That's a great question! You're absolutely right that we can use the round-off value of Delta Xm to calculate the percent error. Keep up the great work!
