biological

-due to uncontrollable variables -variations in a series of observations (same observer) -affect measure pprecision -intermediate

random error

-with definite value and identifiable cause -same magnitude or replicate measurements made the same way -it can lead to bias and can affect accuracy of results -determinte

systematic error

-occur onlyoccasionally, are often large, and may cause a result of either high or low -often a product of human error

gross error

closeness of result and the true value

accuracy

closeness of the result to each other

precision

results are directly proportional to the concentration of the sample
