Random sampling is a sampling technique in
which each sample has an equal probability
of being chosen. A sample chosen randomly
is meant to be an unbiased representation of
the total population.
The Fish Bowl draw is an easy procedure if the total population is small. Each element is numbered on separate slips of paper which are kept into a box; and the required number, according to the sample size decided, is randomly picked out one by one.
Two (or more) samples are called independent if the members chosen for one sample do not determine which individuals are chosen for a second sample. Two (or more) samples are called dependent if the members chosen for one sample automatically determine which members are to be included in the second sample. Fish bowl method can be used for collecting either. The method is random, so, not structured.
