Stratified Sampling A StepbyStep Guide with Examples
In a stratified sample, researchers divide a population into homogeneous subpopulations called strata (the plural of stratum) based on specific characteristics (e.g., race, gender identity, location, etc.). Every member of the population studied should be in exactly one stratum.

Stratified Sampling Vs Cluster Sampling with Examples Meaning and Comparison YouTube
Random Sampling: his method gives every item of the population an equal chance of selection. Systematic sampling involves choosing items at regular intervals. Stratified random sampling is a method of sampling that involves the division of a population into smaller groups known as strata. Quota sampling is a non-probability sampling technique.

Systematic Sample (such as every 4th) Stratified Sample (randomly, but in ratio to group size) Cluster Sample (choose whole groups randomly) Random Sampling The best way is to choose randomly Imagine slips of paper each with a person's name, put all the slips into a barrel, mix them up, then dive your hand in and choose some slips of paper.
Stratified sampling Variation Theory
Stratified sampling is a method of obtaining a representative sample from a population that researchers have divided into relatively similar subpopulations (strata). Researchers use stratified sampling to ensure specific subgroups are present in their sample. It also helps them obtain precise estimates of each group's characteristics.
