IV/DV VARIABLES
what is the independent variable?
what is, the variable that is being manipulated in an experiment.
What is a true experiment?
What is, an experiment where the researcher manipulates the independent variable to measure the dependent variable in a controlled setting.
What is the participant allocation process of a True Experiment?
What is, random allocation.
What is an extraneous variable.
What are variables that can potentially change the relationship between the independent and dependent variable of a study.
controlled variables.
What is the dependent variable?
what is the variable that is being tested in measured in an experiment.
what is, an experiment where the researcher does not have full control over the independent variable.
In what type of experiment is the Iv not manipulated?
What is a natural experiment.
what is situational variable.
Related to things in the environment that may impact how each participant responds.
What are controlled variables also called.
Constant variables
How does shoe size affect running time? What is the Independent Variable?
What is shoe size.
What is a field experiment?
What is, an experiment conducted in a real life setting
What is construct
What is a mental process that cannot be seen or proven.
What is participant variable.
Related to the individual characteristics of each study participant that may impact how they respond.
Confounding variables.
What are variables that can potentially change the relationship between the independent and dependent variable and are unpredictable.
How does shoe size affect running time? What is the dependent variable?
What is, running time.
one limitation of field experiments.
What is, there can be many confounding variables?
You use this to calculate statistical significance in a true experiment.
What is p-value?
A researcher is curious to find out what effect classical music has on people's level of relaxation. He lets one group listen to classical music for one hour. He lets another group sit in a quiet room for one hour.
what's the IV, DV, and ev
IV: listening to music or not
DV: relaxation levels
EV: natural relaxation levels
What are extraneous variables that are not controlled for before the study begins called.
Confounding variables.
what is the independent variable and dependent variable of the Passamonti et al 2012.
IV: serotonin depletion vs Placebo effect
DV: Activity of the pre-frontal cortex during experiment
What is a true experiment.
What was being studied in HM's case study.
His actions after getting his hippocampus removed.
A researcher is studying the effect of sleep on aggression thinking that less sleep will lead to more aggression. She has more people sleep 6 hours per night, some people sleep 3 hours per night and some people sleep as much as they want.
IV: sleep
DV: agression
EV: Natural aggression levels
