Detailed explanation-1: -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.

Detailed explanation-2: -Independent measures design, also known as between-groups, is an experimental design where different participants are used in each condition of the independent variable. This means that each condition of the experiment includes a different group of participants.

Detailed explanation-3: -What is random allocation? An attempt to control for participant variables in an independent group design which ensures that each participant has the same chance of being in one condition as any other.

Detailed explanation-4: -What type of experimental design is affected by order effects? What can researchers do to address order effects and how does this fix them? Counterbalancing addresses order effects by varying the order in which the levels of the independent variable are presented to the participants.

Detailed explanation-5: -More Than Four Conditions. With 5 conditions you need multiples of 120 (5x4x3x2x1), with 7 you need 5040!
