# About mean absolute error and standard deviation

I've calculate the "mean absolute error" for my predicted data and I want to calculate the standard deviation of an error to find the $$\pm$$ range from mean absolute error. The question is do I need to take the absolute to every data points because I've using the mean absolute error. So it's gonna be the same assumption.

• Hi: you should define your terms because the definitions can vary and it's not clear what exactly they are referring to. Nor is +- range. Sounds like you want a CI for something but it's not clear what. – mlofton Apr 12 '19 at 5:00
