Question

Random assignment explain which one is correct and which one is incorrect

Can be achieved by flipping a coin or using a random number table/generator

Requires that every person in the sample has an equal probability of being assigned to any condition.

Is used to achieve the goal of initial equivalence

a & b & c are correct

a & c are correct

Answer 1

All the statements a, b, c are correct.

Random assignment means every unit is ramdomly assigned to different groups in an experiment.

Random assignment can be done with help of some chance procedure. Flipping a coin and random number generator are some of the chance procedures.

For a random assignment, every unit must have equal chance of getting selected and equal change of being assigned.

Random assignment also helps to control equivalence in the initial phase of the experiment as well as to control variables during the experiment.
