For our semester project, we are using sampling technique.

• Sampling means selecting smaller units from the population to study about particular activity.
• It is mainly used in research purpose. Instead of applying experiment over the entire population, few samples are tested and conclusion is drawn based on the outcomes from the selected samples.
• Sampling error occurs when the units chosen for the purpose of study does not match with the expected results.
• For example, to study the food habits of college students in a city.
• Instead of making survey with every student in every college, from each of the college, a few students are asked and finally conclusion is drawn on what type of food is preferable by which group of students.
