Unit Introduction

Knowingly or unknowingly, we take several decisions based on sampling in our daily life For example, when we go to the market to buy grapes, we taste a few to decide whether the entire bunch of grapes is sweet and fresh. Similarly, when a teacher asks questions to a few students in the class to test whether they have understood the lesson or not, it means that the teacher is using sampling.

This course will introduce you the importance of Sampling in Survey research and introduces you to the different sampling techniques available to the researcher. If you want to want to be a good researcher and select a representative sample, this lesson will be an excellent resource for you.

Learning Objectives
