Answer 1

Answer:

Changing origin is same as adding some constant to values and if we add a constant to values, the dispersion of the values from the mean is not changed, so the variance is not affected and remains the same. But if we multiply our values by a constant. Therefore it is independent of origin but not of scaling.
