Stratified sampling is a method to pick certain number of records from each population sub-group randomly. You must be able to categorize the population in one or more stratification or classification. For example, a teacher picks 2 girls and 2 boys randomly from a class of 20 students. Here gender is the stratification method.
Why Sampling is Important?
In the modern business, there are millions of transactions processed every day. To ensure the accuracy of the transactions, each business picks few transactions and audit them as per defined checklist or audit parameters. Picking the right samples is also a big task, you must follow basic rules to pick the samples:
- The samples must not be biased. For example, picking samples of a specific agent or country and not including other agents or countries in the samples
- Samples should be picked randomly and not in a specific order. For example, picking samples of a specific date instead of picking from entire month
- Samples should be picked with a defined rule so that it represents entire population
