A method of assigning people to groups in an experiment that gives each person an equal chance of being in each group. The procedure helps to ensure that groups are comparable before the experimental manipulation begins.
The process of putting study participants into groups (“experimental” or “control”) purely by chance.
In experimental design, the random placement of participants in experimental versus control groups in order to insure that all groups are matched at the outset of the experiment.
Individuals are placed into groups or treatment conditions in such a way that each person has an equal chance of being selected for any group or treatment. In addition, placement of any individual into a group or treatment condition does not influence the placement of any other person.
Placement of research participants into experimental conditions in a manner which guarantees that all have an equal chance of being exposed to each level of the independent variable.
the process of placing research subjects into either intervention or control groups in such a way that each individual in each group is assigned entirely by chance. That is, each subject has an equal probability of being placed in each group.
A method of assigning participants to the various conditions of an experiment so that each participant in the experiment has an equal chance of being in any of the conditions.
A chance method, like flipping a coin or pulling numbers out of a hat, that assigns a participant to an experimental group or to a control group in a clinical study
The assignment of individuals in the pool of all potential participants to either the experimental (treatment) group or the control group in such a manner that their assignment to a group is determined entirely by chance.
The use of random methods to assign different treatments to patients or vice versa.
Assignment of subjects to different treatments, interventions, or conditions according to chance.
Random assignment or random placement is an experimental technique for assigning subjects to different treatments (or no treatment). The thinking behind random assignment is that by randomizing treatment assignment, then the group attributes for the different treatments will be roughly equivalent and therefore any effect observed between treatment groups can be linked to the treatment effect and is not a characteristic of the individuals in the group.
