# Prediction Error Calculator

Prediction error is the measurement used widely in chemistry and other areas of science. It measures the difference between the measured or experimental value and a true or exact value. Percent error is often expressed as positive value. Use this online prediction error calculator to find the Mean (Average) Absolute Prediction Error Calculation. Provide the X value and Y values separated by commas and also the slope and constant value to know the average absolute error value.

#### Formula:

μ = ( ∑ abs(y-y') ) / n
**Where,**
μ = Average Absolute Prediction Error
y = Data
y' = Predicted Data
n = Number of Data
