  Generalised dichotomic quantum measurements are fully characterised by two
real parameters, dubbed as sharpness parameter and biasedness parameter. The
trade-off between the degree of joint measurability, sharpness and biasedness
of generalised measurements was known in the case of pairs of qubit
observables. In the present work we generalise the notion of sharpness and
biasedness measure of multi-outcome generalised measurements pertaining to
multilevel systems. A trade-off between the amount of quantum mechanical (QM)
violation of macrorealism (MR), sharpness and biasedness is established.
Specifically we found that the minimum value of sharpness parameter, above
which the QM violations of different necessary conditions of MR persist,
decreases with increase in biasedness. We also analysed the effect of
biasedness parameter on the magnitudes of QM violations of different necessary
conditions of MR for multilevel spin systems.
