Systematic and gross error are controllable, random error is not. Knowing the type of error can lead to a solution. Systematic error arises from the experimental design and affects the result in one direction, up or down. Gross error arises from an undetected mistake that causes the measurement to be greatly different than the average. This measurement is called an outlier. Scientific Notation.
