Question
Please, as you can see (first picture), I have already calculated the values of k and the average value of k, however in question #4 (second picture) I am asked to estimate its uncertainty, and deviation for each column (please show at least one exemplo). it explains how-but I do not get it. Please note that I have no clue of what I am supposed to do here in question #4, and I really need help. I have posted this question three times already, and have not got the right answer. Thank You In Advance!

Explanation / Answer
I am giving you a complete calcualtion for that
1) Find the average of the measurements= 0.001204
2) Find the variance of these measurements.
a) To do this, first, find the difference between each of the measurements and the average.
b) sQuare the variance
3) Avergae =
4) Find the standard deviation. To find the standard deviation, simply find the square root of the variance
= 0.000248
This is uncertainity
