hindsight bias

blind experiment In a ‘double-blind’ experiment two participants – usually the subject and observer – are uninformed, and in ‘triple-blind’ experiment the subject, the observer, and the person responsible for the actual administration of the drug are left unaware of the nature of the material administered.

When conducting an experiment, it is not only important to manipulate the factors of interest, researchers must also make sure to: keep other factors constant. In an experiment, participants are often assigned to one of two groups.

A correlation coefficient is a statistical measure used to assess the extent to which two factors vary _____ and therefore how well the variables predict each other. Dr. Adams is conducting a study about the relationship between short stature and shyness. Clyde is about to design his first drug-treatment study.

Humility, curiosity, and skepticism. What are the three key attitudes of scientific inquiry? An educated guess or prediction at answering a scientific question that is testable.

Ethics refers to the correct rules of conduct necessary when carrying out research. We have a moral responsibility to protect research participants from harm. However important the issue under investigation psychologists need to remember that they have a duty to respect the rights and dignity of research participants.

For this to happen, use of secondary data must meet some key ethical conditions:

• Data must be de-identified before release to the researcher.
• Consent of study subjects can be reasonably presumed.
• Outcomes of the analysis must not allow re-identifying participants.
• Use of the data must not result in any damage or distress.

What’s the difference between qualitative and quantitative research? Quantitative data is information about quantities, and therefore numbers, and qualitative data is descriptive, and regards phenomenon which can be observed but not measured, such as language.
