just google it bro
Explanation:
absolute error;
The approximation error in some data is the discrepancy between an exact value and some approximation to it. An approximation error can occur because: the measurement of the data is not precise due to the instruments. or approximations are used instead of the real data.
mean absolute;
The average absolute deviation about any certain point of a data set is the average of the absolute deviations or the positive difference of the given data and that certain value. It is a summary statistic of statistical dispersion or variability.
relative error;
Relative Error as a Measurement of Precision. Relative error (RE)—when used as a measure of precision—is the ratio of the absolute error of a measurement to the measurement being taken. In other words, this type of error is relative to the size of the item being measured.
mean percentage;
A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction. All of something is 100 percent, half of it is fifty percent, none of something is zero percent. ... A percentage can also mean a portion of something but only when it has to do with numbers.
