I think activity means activity coefficient if it is that then it it is very easy to answer your question. Generally partial pressure term is used when there is mixture means more than one compund is present in the mixture then we use partial pressure. But if non ideal liquid mixtures are there then we use fugacity coefficient and compressibility factor to describe the non ideality. To measure the extent of deviation from ideality is measure by activity coefficient.

a=f/p,activity coefficient describes the deviation in ideal behavior of any liquid when it a non ideal mixtures ,which is dimensionless
