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.

Which one is called non probability sampling a. cluster sampling b.quota sampling c. systematic sampling d. stratified sampling?
Answer is Quota sampling. Its one of the method of non-probability sampling.
What is sampling in research?
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.

What is the difference between quota sampling and cluster sampling
Mention different types of sampling in statistics.?
Simple Random Sample Stratified Random Sampling Cluster Sampling Systematic Sampling Convenience Sampling
What is a dry sampling?
What is a dry sampling?
What sampling method?
Random Sampling
Are the sampling techniques the same for solid liquids and gases?
No, sampling techniques differ for solid, liquid, and gas samples. For solids, techniques like grab sampling or core sampling are commonly used. Liquids can be sampled using methods like grab sampling, pump sampling, or composite sampling. Gases are typically sampled using techniques like grab sampling, passive sampling, or active sampling using pumps or sorbent tubes.
