Sampling
Stratified & Random
Stratified Sampling
Random sampling refers to sampling via which every member of the target population has an equal chance of making it to the sample. Assign numbers and choose random, place names in a box and select.
Random Sampling
Stratified sampling is when the demographic characteristics of the target population are reflected in the sample. For example, if there are 1% working females in a target population, then the sample should also have 1% working females.
