1.Â Â Â Â Â What do you mean by non-probability sampling?

As the name suggests, this is a type of sampling method in which the given components of the population lack equal chance of participating in a given study. In short the members donâ€™t get equal chances during a study. It is the opposite of probability sampling where all the members get equal opportunities/chances in a given study.

Convenience sampling

i.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Cheap

ii.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Efficient

i.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Depicts high levels of sampling error.

ii.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Vulnerable to selection bias

iii.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Studies depict chances of little credibility.

Judgement sampling

i.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Does not require any special knowledge of statistics

iii.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â No time wasting playing along with digits

i.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â No logic to the selection of its sample or the size

ii.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â It is unscientific

Quota sampling

i.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Has extra information which helps to speed up the sampling process

ii.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â It is time saving

iii.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Has a high level of accuracy since it is considered scientific
