Ensuring that no psychological or physical harm is caused to the research participants and the researcher must also respect the participants’ rights as individuals.
Participants have a right to privacy, so all details of their involvement in the study cannot be revealed in a manner that enables the individuals to be identified.
The researcher must try to ensure that participants’ involvement in the research is voluntary. Participants must not be placed under any pressure to take part in the study.
Participants must be appropriately informed of the nature and purpose of the investigation. Such informed consent must be documented and a consent form signed by the participant which is required before the experiment.
A participant must be permitted to withdraw from a study at any time, without giving a reason, should they wish to do so.
Deception in Research
Sometimes if the participants are told too much information about a study may influence their behaviour during the research and affect the accuracy of the results. When the researcher does not fully inform the participants of the study, they must ensure that the participants are not under too much distress from the procedure.
The researcher must provide an opportunity for participants to obtain appropriate information about the nature, results and conclusions of the research. Participants must be informed of the purpose of the investigation at the conclusion of the research. The researcher must correct any mistaken attitudes or beliefs that participants may have about the research.
The benefits of the study must outweigh the harm.
Limitation of experiment
- time (length of experiment)
- sample/population size (may/may not represent whole population)
How to make fair test?
- same amount liquid etc
- same pop. size
- same people if possible
- Independent x-axis (bottom)
- dependent y-axis (side)
