Population Parameter
It is a sampling method in which units are selected based on easy access/availability. The disadvantage of convenience sampling is that the units that are easiest to obtain may not be representative of the population. For example products on top of a box of parts may be a different quality from those at the bottom, people who are at home when the market researcher calls may not be representative of the entire population. It is also called as Accidental Sampling.
It is called rationalisation [of the denominator].
