Measurements and their Errors
Cards in this deck (6)
- 1How do you find uncertainty from a range of values?Find the mean of the values, then see how far this is from the furthest values. This is the uncertainty
- 2How do you find uncertainty from a single measurement?Find the sensitivity of the instrument used, then half this to find the uncertainty
- 3How do you find uncertainty from several measurements?The mean value needs to be of the same precision of each reading
- 4How do you find percentage uncertainty?(uncertainty/value)x100
- 5What do you do the uncertainties of values when you add them?Add the uncertainties
- 6What do you do to the uncertainty if the value is raised to a power?Multiply it by the number of the power
