Identify Strata

In statistics, strata refer to the subgroups that make up a population. Identifying strata is important in sampling and data analysis as it helps in creating a more representative sample of the population.

Why Identify Strata?

Identifying strata helps in ensuring that a sample is diverse and representative of the entire population. This is important because it reduces the chance of bias and provides more accurate results when making inferences about the population based on the sample data.

How to Identify Strata?

To identify strata, you need to first understand the characteristics of the population you are studying. These characteristics could include demographic factors such as age, gender, income, education level, and so on. Once you have identified these characteristics, you can then group the population into subgroups based on these characteristics.
