Answer #1

(A) Correct, because systematic systematic errors are not random because these error occurs after a fixed interval or frequency.

(B) Correct, because if we know how much error is present in system, then we can subtract that error from each observation to get the true scores

(C) Correct, because systematic error are due to incorrect calibration, but if we do proper calibration, then error can be reduced.

(D) Correct, because the error occur after a fixed interval and in the same direction, due to which it produces values which vary in one direction from the true scores

(E) incorrect, error due to researcher fatigue is not systematic error.

Option A, B, C and D are correct.
