percentage uncertainity

[hafza89]

guys how do we calculate uncertainities and percentage uncertainities

[Blue_Ice]

% uncertainty= actual(absolute)uncertainty/ true value

and when u r doing an experiment and u want to find the absolute uncertainty, repeat a certain measurement twice, then

absolute uncertainty= 1/2 (range)

the range is the difference between the two mesurements

[phoolan_rani]

then we no need to see smallest division on d ruler or any equipment....

[Blue_Ice]

u can do tht too 

absolute uncertainty= smallest division/ true value

both r correct

and when u r doing an experiment and u want to find the absolute uncertainty, repeat a certain measurement twice, then
absolute uncertainty= 1/2 (range)
the range is the difference between the two mesurements

explain absolute uncertainity.......o.5 [range]
i dont get it

u repeat the reading twice, then subtract the two readings (thts the range), then divide by two to get the absolute uncertainty
