Detailed explanation-1: -A strength of the independent measures design is that because participants only take part in one condition participants are less likely to become border or practiced and therefore the experiment is more likely to measure natural real-life behaviour.
Detailed explanation-2: -However, the disadvantage of independent measures design is that there is the potential for error due to individual differences between the groups of participants. A repeated measures design consists of testing the same individuals on two or more conditions.
Detailed explanation-3: -You need twice as many participants so it is time consuming. Individual differences or participant variables may make the comparisons unreliable, so you can use random allocation which may balance it out as everyone has an equal chance of being selected for each condition.
