Process vs. Content – a way of obtaining knowledge that can be applied to
all content areas
Can use this course (process) as a knowledge compatible with all other
content (research areas)
Critical Thinking- it gives you a way of thinking about facts and testing them.
Chapter 5- Experimental Research
The experimenter varies one or more variables while holding others
Advantage- it allows you to infer cause-and-effect.
Disadvantage- generalizability? Experiment often conducted in artificial
laboratory environment and may lack generalizability in the real world.
INDEPENDENT VARIABLE (aka IV):
The variable that the experimenter changes in order to see if or
how it affects behaviour.
DEPENDENT VARIABLE (aka DV):
The behaviour that’s measured to see if the independent variable
had an effect.
EXTRANEOUS VARIABLE vs. CONFOUNDING VARIABLE
Extraneous Variables- are variables that are not controlled and are of no
interest to the researcher. They are not problematic as long as they are held
constant. *think of the word “extra” as extra stuff that doesn’t matter*
Confounding Variable- its an uncontrolled extraneous variable that changes
with the independent variable and can also affect the dependent variable. It is a variable that you do not want in your study because it tosses your
experiment out the window and you must start from scratch. An extraneous
variable “gone wild”.
In an experiment, all groups MUST be equal to one another in every way
except for the IV.
Control Group- the group that gets the “0” amount of
