Repeated Measures Design Using Privileged Words

Repeated measures design was used in this experiment because the condition using black words was used as a control against the condition using coloured words. Therefore, participants would have to have taken part in both conditions to act as a control variable as different participants would have different capacities, in terms of STM. A repeated measures design is when the same group of participants take part in both of the conditions of the study that is being carried out. The key variable within this experiment is the independent variable of words being written in colour or in black. The independent variable is whether the words were written in colour or in black, and the dependant variable was the amount of words that were recalled in each condition by all of the participants. An example of an
Therefore, this can easily be overcome by not giving out the scores of the participants to ensure that they do not become stressed over knowing their results in both conditions. 8 participants were used in this experiment and were all aged 17 however, both males and females were used in this investigation. The sampling method that was used was random sampling to ensure that a biased sample was not used, on reason a biased sample was not used is that participants weren’t selected for certain reasons, and another reason is that it prevents a certain group of participants from applying to take part in the study. Participants were not allocated to certain groups in this investigation because, although there were two conditions, each participant took part in both conditions therefore, participants didn’t have to be allocated to specific groups. Each participant was tested individually, in a room without distractions in order to ensure that their full concentration was on the
