Pilot studies (and more) Flashcards
What is a pilot study?
A small-scale version of an investigation that takes place before the real investigation is conducted. The aim is to check that procedures, materials, measuring scales etc work. The researcher can also make changes/ modifications if necessary.
When can pilot studies be conducted?
On any experiment including questionnaires and interviews.
What is a single-blind procedure?
Where the participants will sometimes not be told the aim of the research at the beginning of the study as well as any details about it such as which condition they are in. This is not revealed until after the study takes place. The researcher is aware of the aims and conditions of the study.
What is a double-blind procedure?
Neither the participants nor the researcher who conducts the study is aware of the aims of the investigation.
When would a double-blind procedure be used?
In a drug trial. Treatments will be administered without the researcher or the participants knowing which drugs are real and which are placebos. If neither knows, expectations cannot influence participant behaviour.
What is a control group?
A group which consists of participants not experiencing the experimental procedure. This group can be used as a comparison. E.g being given a placebo in a drug trial.
What happens if the change in behaviour of the experimental group is significantly greater than the control group?
The researcher can conclude that the cause of this effect was the independent variable.
