What is Sample ? Sample is the part of population which is representative of that population. A sample is the group of people who take part in the investigation . It is a smaller, manageable version of a larger group. A researcher cannot directly make observation of every individual in the population for the study , so that's why he select a subset of individuals {sample} . Example:- Suppose, the total population of the collage is 7000 and a researcher choose only 100 boys and 100 girls for his study .

[ Chaplin, 1975, P- 468 ] " Sample refers to a selection of scores from a total set of scores known as the population." ...
