uncertainties Flashcards
Random error
these are unpredictable errors brought about by things usually out of your control
systematic error
these are errors usually brought about by the measuring equipment or its operator
how to reduce random error
repeating readings
how to reduce systematic error
calibrating equipment
accuracy
how close it is to the true value
precision
how close the reading are together
how to improve accuracy
reducing systematic errors
how to improve precision
reducing random errors
systematic uncertainty
± smallest divine on the instrument
random error uncertainty
find the mean results ± the biggest difference
adding or subtracting uncertainties
add uncertainties
multiply or dividing
add the percentage uncertainties
A x B or A / B
add percentage uncertainty of A with percentage uncertainty in B
A^2
double the percentage uncertainty of A
UNCERTIANTY
finest division / reading taken x100%
