I have been given a problem to solve based on uncertainty of measurements, however I have no idea what I am doing since I am a computer student and not a maths student (No idea why they have given me this!!!)
There is probably a really simple answer, but I am completely out of it when it comes to maths and stats..
I won't post my actual problem as I would like to work that out myself, but below is a similar problem:
set1: Bill measures the length of 10 wires. His results are (in metres): 4.7, 4.8, 4.9, 4.9, 5.0, 5.0, 5.1, 5.1, 5.2, 5.3.
set2: Bob measures a different batch of 10 wires and gets a mean of 5.3m and a standard deviation of 0.2m
and from this I worked out the following about set 1:
- precision = 0.1m
- mean = 5
- standard deviation = 0.1826
- accuracy = 5 +- 0.1826
- standard error = 0.0577
- 95% confidence interval = 4.887 <= x >= 5.113
- significance between both samples value using t-test = 3.323
I got given some really helpful slides by my lecturer to help me work out those above, however nothing is mentioned on uncertainty
So.... What value of uncertainty would you estimate for the measurements?
Any steps on how to work this out would be great!!
Also examples of how to write uncertainty would be great too!!
