This sampling method is usually employed in studies that are not interested in the parameters of the entire population.Some researchers prefer this sampling technique because it is cheap, quick and easy.In this type of population sampling, members of the population do not have equal chance of being selected.
Difficulties conducting surveys in these locations may explain this disparity.
We propose a generalisable, scientifically valid method that is sustainable and ensures community engagement.
The idea of gathering data from a population is one that has been used successfully over the years and is called a census.
It was also used by the Ancient Egyptians “to obtain empirical data describing their subjects”.
Still, every researcher must keep in mind that the ideal scenario is to test all the individuals to obtain reliable, valid and accurate results.
If testing all the individuals is impossible, that is the only time we rely on sampling techniques.
It can also be used to estimate the population parameters since it is representative of the entire population.
It is also a reliable method to eliminate sampling bias.
In probability sampling, every individual in the population have equal chance of being selected as a subject for the research.
This method guarantees that the selection process is completely randomized and without bias.
