I know I know..you all have it figured out by now..now its my turn..
- I agree with almost all of you, according to me for a single researcher, it will be virtually impossible to achieve the objective.
- I think so because the researcher will single handedly have to interact with all the individuals in the population. Moreover a lot of time, money and energy will be required.
- In such a case what the researcher could do is, find out people who can help him/her with the study in different parts of the country. But so many people won't do work for free and may also not have the time, thus if s/he thinks of employing help then they would have to payed for it. But what if the researcher does not have the resources for it? Then what would s/he do?
- The solution of course lies, as some of you stated (you girls are good at this..), in sampling! (finally we come to it!), by sampling we mean s/he would select individuals that represents the population. This makes the population easy to handle and also saves on resources like time, money, energy.
These selected individuals constitute the so often heard sample.
The process of selecting individuals from a population is called sampling technique/ sampling strategy/ sampling design. The following illustration is a simple representation of population and sample.

But conversely it is also true that if the population under consideration is small then there is no point in sampling. So if the population itself is limited to the students of class A in schoolXYZ then there is no need to sample within this lot again.

hi hemangi good morning
well hemangi you said that if a researcher doesnt have resources and population is large than s/he can go for sampling but in this case also s/he will require help inorder to select the representative sample right because s/he cannot find the representative sample of enitre India alone and if resources are a problem so what a researcher can do.
Hi Hemangi!! you are really making an topic easy for us to study. language is very simple and especially examples are very strong which makes it more easier to understand the concepts.
i just wanted to clear one doubt that 'sampling unit' is the samples which you are studying and also 'samples' are the group of people on which study is conducted then what exactly is the difference between them ?
