Trial 3: 1.5 m.
Trial 4: 1.05 ± 0.05 m.
Homework Equations
Not sure
The Attempt at a Solution
So to add them up, I just add the "base" measurements" and then tack on the ± and stick in the "uncertainties" like so:
1.05 + 2.0 + 1.5 + 1.05 = 5.6 m.
±
0.05 + 0.05 = 0.1 m.
So the final sum: 5.6 ± 0.1 m.
Now to take the average, I need to the quotient of 5.6±0.1 / 4 but not sure how to do this. The instructions say to divide the averages of the two numbers you are trying to divide (5.6 / 4) and them multiply that quotient by (1.00±δ5.6/5.6 = δ4/4) but 4 doesn't have an average deviation because it's just a number.
So how do I do this?
