formula for best estimate of g (gbest)
1/N ∑gi
5
New cards
formula for uncertainty of average result (Δgbest)
sqroot(1/N ∑(Δgi)²
6
New cards
average in quadrature
method of squaring errors averaging this squares, and taking sqroot of the average
7
New cards
why are errors averaged in quadrature?
to account for the fact more measurements provide a better estimate rather than adding the errors together
8
New cards
standard value to g in SI units
9.8 m/s²
9
New cards
how to handle outliers
recalculate best value and its outlier and compare new value to original using δ
