Understanding correlation vs. experimental research
Scientific method: a procedure of finding truth using empirical evidence
The process of describing, plaining, predicting, and controlling variables
Descriptive research: describes with characteristics of a population or phenomenon
Often deal with frequency and percentages
Ex. What % of people support a basic income?
Correlational research allows us to determine if two variables are related DOES NOT allow
us to make inferences about causation
The result would give us information about the relationship between studying and exam grades.
WE COULD NOT CONCLUDE THAT STUDYING CAUSED THE STUDENTS
GRADES.
Other possible causes:
Intelligence
Number of lectures attended
How much sleep the student got before the exam
All could have an impact on the exam grades
Results:
Correlation coefficients described
How do we infer causation?
Preform an experiment
Two key factors of experiments:
Manipulation: changing a variable to determine its causal power
The variable that is manipulated is the IV
This creates two groups
Experimental group
The control group
The variable that is measured is the DV
Random assignment: a procedure that allow chance to assign people to the experimental group
or the control group. (ALL HAVE AN EQUAL CHANCE OF GETTING IN TO EITHER
GROUP)
Quasi experimental research:
Includes manipulation
Random assignment not possible
May be unethical or impossible (sex, age, gender)

Ex. Impact of age on exam grades
We could divide participants into two or more groups based on their age
Compare grades between students in each age group
**Can still infer causation**
thinking critically identify assumptions that are made and then challenge them.
