Step-by-step explanation:Stratified sampling refers to a type of sampling method, in which the population get divided into separate groups which are referred to as strata. A researcher then chooses randomly from these strata, a simple random sample which will be truly representative of that society since everyone who is anyone stands an equal chance to be chosen.
