Manipulated Variable in Siri's Study: Redheads vs. Brunettes

What is the manipulated variable in Siri's study comparing redheads and brunettes?

A. A manipulated variable

B. A construct

C. A measured variable

D. A constant

Answer:

The 'redheads vs. brunettes' factor in Siri's study is the manipulated variable, as this is the attribute that is deliberately changed to observe its impact on people's frustration levels.

In Siri's study, the factor 'redheads vs. brunettes' is considered the manipulated variable. This means that this specific characteristic is intentionally altered by Siri to analyze how individuals respond to frustration based on their hair color. The manipulated variable, also known as the independent variable, is the element in an experiment that researchers deliberately modify to study its effects on behavior or reactions.

By changing the 'redheads vs. brunettes' variable, Siri is able to investigate the correlation between hair color and the way individuals express frustration. The response to frustration, whether it involves yelling or not, is then measured as the dependent variable or the measured variable in this study.

It is essential in psychological experiments to identify and manipulate variables to understand the causal relationship between different factors. In this case, Siri's study on redheads versus brunettes exemplifies the manipulation of a variable to explore its influence on human behavior.
