## Homework Statement

Quick question, working on a lab

Just wondering how I could go about getting an average value for a series of figures with +- values.

For instance

1) 1.5 ± 0.02

2) 1.7 ± 0.84

3) 1.7 ± 0.08

## The Attempt at a Solution

I tried enclosing the figures within parenthesis and then trying to find an average with wolfram alpha but no success.

I was just reading something on the net

would it be x "avg" ± Δx "avg

1.5 + 1.7 + 1.7 /3 = 1.63

(sqrt) 0.02^2 + 0.84 + 0.08 = 0.844

so we arrive at 1.63 ± 0.844

correct ?
