Percentage Error is: ~1.4% (1.39049826188%)
Percentage error = 100*error/standard = 100*(3.98-3.14)/3.14 = 100*0.84/3.14 = 84/3.14 = 26.75%
The answer depends on whether the rounding is to the nearest hundreds, the nearest tens or nearest unit!
There is no error. That's why it's impossible to find one.
we can find the zero error by closing the jaw of screw guage if the zero of main scale(MS) is concide with the zero of circular scale (CS) there is no zero error and if they are not concide there is a zero error in screw guage .
Generally speaking an x% confidence interval has a margin of error of (100-x)%.
: Find the percentage error if 625.483 is approximated to 3 significant digits?
Go find out.Or:(calculated value) - (actual value)---------------------------------------- * 100(%) = percentage of error(actual value)(if the top value is negative, just switch the two or multiply by -1)

ERROR is the experimental value-accepted value.
to find the percentage of the relative error
=(A1/B1)*100 then press Ctrl + Shift + % and the cell will be displayed as a percent
Percentage error = 100*error/standard = 100*(3.98-3.14)/3.14 = 100*0.84/3.14 = 84/3.14 = 26.75%
what is the number supposed to be if you git 7 cm? Percent error is the percentage that you're incorrect by, so you need another measurement. to do it, you find the difference and then divide by the original so (7-x)/true value then multiply by 100 to get percentage.
The answer is that I would try to find out what he understands about rounding and then explain the concept of rounding through examples that he can identify with.
You find its approximate value, in the context of the degree to which you are rounding.
approximate
.the same but you just round the numbers first
