When the value of λ is small, and if the value of EWMA is on one side of the CL and the shift of mean occurs in the opposite direction, EWMA takes several periods to react to that shift. This is called _____

When the value of λ is small, and if the value of EWMA is on one side of the CL and the shift of mean occurs in the opposite direction, EWMA takes several periods to react to that shift. This is called _____ Correct Answer Inertia effect

The staying of EWMA on a side till a very heavy shift occurs in the process mean; is called the inertia effect of the EWMA charts. This occurs only when the value of λ is very small.
