IV/DV VARIABLES
TYPES OF EXPERIMENTS
TYPES OF EXPERIMENTS 2
Extraneous Variables
Controlled and Confounding Variables
200

what is the independent variable?

what is, the variable that is being manipulated in an experiment. 

200

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.

200

What is the participant allocation process of a True Experiment?

What is, random allocation.

200

What is an extraneous variable.

What are variables that can potentially change the relationship between the independent and dependent variable of a study.

200

controlled variables.

What are variables that are left constant to avoid influencing the relationship between the IV and DV. 
400

What is the dependent variable?

what is the variable that is being tested in measured in an experiment.

400
What is the difference between a quasi-experiment and a true experiment? 

what is, an experiment where the researcher does not have full control over the independent variable. 

400

In what type of experiment is the Iv not manipulated?

What is a natural experiment.

400

what is situational variable.

Related to things in the environment that may impact how each participant responds.

400

What are controlled variables also called.

Constant variables

600

How does shoe size affect running time? What is the Independent Variable?

What is shoe size.

600

What is a field experiment?

What is, an experiment conducted in a real life setting

600

What is construct

What is a mental process that cannot be seen or proven. 

600

What is participant variable. 

Related to the individual characteristics of each study participant that may impact how they respond. 

600

Confounding variables.

What are variables that can potentially change the relationship between the independent and dependent variable and are unpredictable.

800

How does shoe size affect running time? What is the dependent variable?

What is, running time.

800

one limitation of field experiments.

What is, there can be many confounding variables?

800

You use this to calculate statistical significance in a true experiment.  

What is p-value?

800

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

800

What are extraneous variables that are not controlled for before the study begins called. 

Confounding variables. 

1000

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 

1000
Type of experiment of the bobo doll experiment

What is a true experiment. 

1000

What was being studied in HM's case study. 

His actions after getting his hippocampus removed.

1000

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 

1000
What type of experiments control for and limit the impact of confounding and extraneous variables the most. 

Experiments in a lab setting.
