The digits in the measurement up to and including the first uncertain digit 


An eqaul probability to be too high or too low when an experimenter approximates a reading. 


Systematic errors occur as a result of poor experimental design or procedure, but these errors do not decrease by repeating the experiments. 


have small random errors and reproducible in repeated trials 


have small systematic errors and give a result close to the accepted value 


absolute uncertainty/measured value 


(absolute uncertainty/measured value)x100 


[(accepted value – experimental value) / accepte value]x100 


Variable that does not change, which plotted in the horizontal axis of the graph 


Variable that changes which is plotted on the vertical axis and gives an indication of the reliability of the measurement 


A line that has to be extended beyond the range of masurements on the graph 


The process of assuming that the trend line applies between two points
