A researcher wants to understand the effect of child abuse on an individual's personality and attitude. He forms two groups of p

Stratified sampling entails the division of a population into different homogeneous groups also known as strata. When a researcher conducting a study does not use the simple random sampling method, but instead chooses to divide the population into homogeneous group that is based on similar characteristics or experience, then such researcher has used the stratified design of sampling.
Stratified random sampling is a design that involves dividing a group into smaller division or strata to get a defined result, this division is based on character or shared attitude. This design is also known as proportional random sampling.
Frictional unemployment refers to the time in which a worker does not have a job because he isseeking for a new one or transitioning from one job to another.
