If i have 3 different uncertainties how do i get the average uncertainty of the three?

For example
±.3 , ±.2 , ±.3

how do i find the average uncertainty of the three?

To find the average uncertainty of three different uncertainties, you need to calculate the mean uncertainty. Here's how you can do it step by step:

1. Add up all the uncertainties: ±0.3 + ±0.2 + ±0.3 = ±0.8.

2. Divide the total uncertainty by the number of uncertainties you have (in this case, 3): ±0.8 / 3 = ±0.27.

So, in this example, the average uncertainty of the three uncertainties ±0.3, ±0.2, and ±0.3 would be approximately ±0.27.
