## Homework Statement

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.

ε

_{a}= √((ε

_{Y})

^{2}+ (ε

_{X})

^{2})

I was unsure however if it was given by the addition of the individual error in each measurement.

Thanks
