AS Psy Research Methods Revision 1

A group of participants are recruited and divided into 2. The first group does the experimental task with the IV set for condition 1 and the second group does the experimental task with the IV set for condition 2. The DV is measured for each group and results are compared.

• Independent measures design

• Repeated measures design

• Matched pairs design

There are no set questions and the participant is given the opportunity to raise whatever topics he/she feels are relevant and ask them in their own way. In this kind of interview much qualitative data is likely to be collected.

• structured interview

• semi-structured interview

A group of participants are recruited. We find out what sorts of people we have in the group and recruit another group that is similar to them as much as possible. The experiment is then treated like an independent measures design and the results are compared.

• Independent measures design

• Repeated measures design

• Matched pairs design

This type of experiment is conducted in a well-controlled environment – not necessarily a laboratory – and therefore accurate and objective measurements are possible.

• Laboratory experiment

• Field experiment

• Natural experiment

____________ sampling is the one in which participants pick themselves through newspaper adverts, noticeboards or online.

• opportunity

• volunteer

• random

An in-depth investigations of a single person, group, event or community. It provides rich qualitative data and has high levels of ecological validity.

• experiment

• self-report

• observation

• correlation

• standarization

• validity

• reliability

• deception

numerical data e.g. reaction time or number of mistakes. It represents how much or how long, how many there are of something.
