MAPE is the mean absolute percentage error, which is a relative measure that essentially scales MAD to be in percentage units instead of the variable’s units. Description Mean absolute percentage error is a relative error measure that uses absolute values to keep the positive and negative error...

Give a brief description about Absolute, Relative and Percentage errors. What is the discrepancy formula in physics? What is percentage error and how can be reduced? The data value x = 45 has a deviation value of 12. What is the meaning of this?
|X – µ| = absolute deviation N = sample size The formula involves absolute deviations. A deviation is the difference between a data point and themean. The absolute value of the deviation simply tosses out any minus signs that occur. If we didn’t use the absolute value, the pluses ...
Mean absolute deviation is the average distance between the mean of a set of numbers. This is used to analyze statistics in many fields. Not only do you find the mean (average), but the distance between each number to the mean. Read Mean Absolute Deviation | Definition, Formula & Examples...
