selection of few units as representative from the totality for study is called sampling. Use of sampling
is being done since ancient times. in daily life also we make a lot of use of sampling method. to know
if the rice is cooked or not, housewives test a few rice. in this way, while buying wheat, rice, pulses etc
from the market, we check by taking out handful of seeds from the sack or while buying mangoes, by
tasting the mango from the bowl, we decide about all the mangoes. By testing only one drop of blood,
doctor infers about the disease. traders for testing molasses, sugar, chilly, coriander, cotton, cloth and
thousands of things, take a sample from the whole and find the conclusion and apply this conclusion
on the whole. in this way, use of sampling is done massively by common man in daily life.
