Assignment treatment Work
Random assignment or random placement is an experimental technique for assigning human participants or animal subjects to different groups in an experiment ( e. , a treatment group versus a control group) using randomization, such as by a chance procedure ( e. , flipping a coin) or a random number generator.
Random selection and random assignment are commonly confused or used interchangeably, though the terms refer to entirely different processes. Random selection refers to how sample members ( study participants) are selected from the population for inclusion in the study. When the population embraces a number of distinct categories, the frame can be organized by these categories into separate " strata. " Each stratum is then sampled as an independent sub- population, out of which individual elements can be randomly selected. The ratio of the size of this random selection ( or sample) to the size of the population is called a sampling fraction.
