What does sampling mean in a scientific investigation?

Answer and explanation

Correct answer: बड़े समूह से अध्ययन के लिए कुछ प्रतिनिधि वस्तुएँ चुनना

Sampling means choosing a smaller set of items or individuals from a larger population so that the set represents the larger group for study. Therefore, option C is correct. Studying every item in the group is a census, not sampling. Exam tip: A representative sample is usually selected fairly or randomly to reduce bias.
