between 37° and 39°) Temperature = 38 ±1° So: Absolute Error = 1° And: Relative Error = 1° = 0.0263... 38° And: Percentage Error = 2.63...% Example: You Skeeter, the dog, weighs exactly 36.5 pounds. But, if you are measuring a small machine part (< 3cm), an absolute error of 1 cm is very significant. A significant figure is defined as a digit that we believe to be correct, or nearly so. have a peek at these guys
