A small scale investigation conducted before the main study
What are 5 problems pilot studies aim to check
1)Experimental design - do the participants have enough time to complete the tasks?
2)Instructions for participants – are the instructions clear
3)Time - If the study is taking up too much of the ppt’s time, not able to continue normal activities for the rest of the day (not conforming to normal standards of the pilot study)
4)Ceiling/floor effects = too easy/hard (this would produce data which would be too difficult to analyse)
5)Data - If there is an even spread of data
Why are pilot studies carried out beforehand?
Is a way to ensure time, effort and money are not wasted on a flawed methodology.
It is important that a pilot study uses a sample that although smaller, is representative of the target population that will be used in the main research.
Give benefits of pilot studies
Prevents full scale, expensive studies being conducted with fixable errors
Saves time
No resources wasted
Protects the professionalism & prestige of the research/psychology as a discipline
Give limitations of pilot studies
Prevents the main study from taking place sooner
May cause lengthydelays
May not be effective in preventing errors from occurring
