accuracy
example of systematic error incorrectly calibrated instrument; consistently
misreads it
random error arises from uncontrolled, and often uncontrollable,
variables in an experiment which has equal chance
of being positive or negative; cannot be detected
or corrected for; affects precision
example of random error Human error and lack of instrument sensitivity
why does ice float on water? ice is less dense than liquid h2o
how does temperature affect the as temperature increases, density decreases
density of a solution?
does calibration using standards accuracy
help improve the accuracy or
precision of the experiment?
What axis is the independent x-axis

what axis is the dependent variable y-axis
