1a. Explain why the researcher may have chosen a quasi-experiment in this research?
Shows the researcher a naturally occurring independent variable on whether the participant regularly plays violent computer games or not.
-> Increased realism and ecological validity
1 of 9
What does that mean?
By letting experiments carry out in a natural setting, the researcher is behaving ethically by not exposing participants to possible harm
2 of 9
1b. Suggest an appropriate directional hypothesis for this research
School children who do not play violent computer games will have a lower number of incidents that indicate aggression recorded by the children's school than children who do play violent computer games
3 of 9
1c. Give one advantage of using a matched pairs design in this research
One advantage -> no order effects as school children were either in the group that regularly played or not regularly playing violent computer games
4 of 9
Another advantage...
It reduces participant variables as the researcher has to pair up the participants for abilities or characteristics which may affect performance to give a direct comparison of their aggression level.
5 of 9
1d. Explain one factor that the researcher may have used to match the participants in this research
The school children could have been matched for age, otherwise, the number of aggressive behaviours might just be because they are young and immature.
6 of 9
1E (i). Draw one conclusion from the range of scores in this research
The group of school children that played violent computer games had a range score (6) that was twice that of the school children who did not play violent computer games (3).
7 of 9
1E (ii). Explain one weakness of using the range scores in this research
As the range score is quite crude, the range scores of the group who play on violent computer games may have been affected by just one anomalous result.
8 of 9
1F. Explain why a peer reviewer might consider researcher bias to be an issue in this research
-> Researcher might interpret the data in a way attributable to the researcher's expectancies or preconceived beliefs due to the psychologist concerned about the impact playing violent computer games is having on the development of school children/
