Manipulation of the Independent Variable This refers to the administration of a program, treatment, or intervention to one group within the study and not to the other subjects in the study.
Manipulation of the Independent Variable Involves the use of control and intervention groups.
Randomization Used when the required number and type of subjects from the population are obtained such that each potential subject has an equal chance of being assigned to a treatment group.
Randomization This eliminates bias, aids in the attainment of a representative sample, and can be used in various designs.
