When a sample of participants have equal chances of being assigned to either the experimental condition or the control condition this procedure is called?
Independent Measures: This means that each condition of the experiment includes a different group of participants. This should be done by random allocation, which ensures that each participant has an equal chance of being assigned to one group or the other.
What is it called when a research subject has an equal chance of being placed in either group?
Random Selection. A method of selecting a sample from a population. Every member of a population has an equal chance of being selected. Increases the likelihood that the sample represents the population and that one can generalize the findings to the larger population.
When each member of the population has an equal chance of being chosen for an experiment the researcher has used?

Is counterbalancing used in between-subjects?
When counterbalancing is used to assign levels of a within-subjects factor to participants, it is a good idea to verify that the desired effect was achieved – that learning was effectively canceled out (i.e., balanced). This is verified by including “group” as a between-subjects factor in the analysis of variance.

Counterbalancing can be obtained through different designs. The major distinctions are between intrasubjects and intersubjects designs, and complete and incomplete designs.
How do you counterbalance?
Counterbalancing is a technique used to deal with order effects when using a repeated measures design. With counterbalancing, the participant sample is divided in half, with one half completing the two conditions in one order and the other half completing the conditions in the reverse order.
