Stratified Random Sampling

STRATIFIED RANDOM SAMPLING

       Definition: Stratified sampling is a type of sampling method in which the total population is divided into smaller groups or strata to complete the sampling process. The strata is formed based on some common characteristics in the population data. After dividing the population into strata, the researcher randomly selects the sample proportionally.

 Stratified random sampling is a sampling method in which a populatio

n group is divided into one or many distinct units – called strata – based on shared behaviors or characteristics.

• 1. Stratified random sampling refers to a sampling technique in which a population is divided into discrete units called strata based on similar attributes, and the selection is done in a manner that is representative of the whole population.
• 2. The sampling technique is preferred in heterogeneous populations because it minimizes selection bias and ensures that the entire population group is represented.
• 3. It is not suitable for population groups with few characteristics that can be used to divide the population into relevant units.

Science and Technology is an integral part of our every day life. We use various kinds of tools and techniques for different purposes, but do you know how they work?.We observe a number of things happening around us. But have you ever thought of the reasons as to why such things happen and why some things are the way they are ?

In fact we all know some amount of science but true meaning of science is to internalize the Method of Science and apply it in our day to day life.Let us explore the World of Science to know more. .
