Physics307L:Schedule/Week 6 agenda/Uncertainties
Steve Koch 11:31, 4 October 2010 (EDT): In 2010, Koch was absent for lecture and both lab sessions due to a nasty cold / bronchitis.
Key today: Need to assign some uncertainty to every reported measurement
Rough estimates are a great start! (and sometimes only way)
Probability density functions -> Cumulative distribution functions
Central limit theorem review
Central limit theorem part II
Mean +/- standard error of the mean
aka "standard error", "standard deviation of the mean"
From a collection of measurements
Central Limit Theorem Part II
- Central limit theorem (I): (Last week) distribution of averaged measurments ... (II): distribution of single measurement as a result of a bunch of small, independent, random errors.
