In statistics, sampling is a process of collecting information from a subset of a population so as to reach conclusions about the whole population. This method is used because collecting information from the whole population is likely to be expensive and time consuming, and in some cases pointless. For example, if you tested the life expectancy of all light bulbs, you would have none left to sell!

It means to take samples. This is often done in statistics; for example, in many cases you can't reasonably interview every single person on Earth, or in a country, so you take samples, and interview a few people. This has to be done carefully, to be reasonably sure that the sample is representative of the entire larger population.

It is a subset of the population in a study.

Answer is Quota sampling. Its one of the method of non-probability sampling.

Sampling techniques in researching involves to types of sampling. The probability sampling and the non-probability sampling. Simple random is an example of probability sampling.

You are correct; convenience sampling is not random sampling.
