A series of 5 measurements of Y are recorded with increasing X. (i.e. gradient has units Y/X)
The error in measurement of Y is ±0.05
The error in measurement of X is ±0.005.
How is the error in the gradient calculated?
Homework Equations- measurements[/B]
Y | X
0.2 | 0.23
0.3 | 0.27
0.5 | 0.31
0.6 | 0.38
0.8 | 0.42
The Attempt at a Solution
I assumed that the error in the gradient a would given by the equation.
εa = √((εY)2 + (εX)2)
I was unsure however if it was given by the addition of the individual error in each measurement.
