What is a case study?
Case study involves analysis of one individual
Correlational study can NOT tell what ____

variable that the researcher manipulates (cause)

Psychology assumes ___________ provides the most accurate knowledge about what is generally true about behavior
The scientific method
what is a correlational study
Observes relationships between two variables (or more) without the researcher controlling or manipulating any of them.
Correlational co-effienct provides info about the _____ and the ____ of the study
Direction and strength
To find the effect of fast food on blood pressure 50 middle aged men where assigned to consume fast food whilst another 50 middle aged men where told not to.
What type of study is this? If experimental study what is the IV and DV and if correlational study is it a positive correlation or negative?
Experimental study
IV=consumption of fast food
DV-Blood pressure
A researcher wants to determine if the color of an office has any effect on worker productivity. One group of workers performs a task in a yellow room while another performs the same task in a blue room.
What type of study is this? If experimental study what is the IV and DV and if correlational study is it a positive correlation or negative?
Experimental study
IV- Color of the office
DV- Worker productivity
What is the disadvantage of a case study?
Often does not generalize to a broad group
What is an experimental study
A study that manipulates one variable to see its effect on another
Define dependent variable
Outcome variable measured afterward (Effect)
The relationship between student absences and overall grades is of particular interest to researchers. The researchers examine 100 student records before looking at the students' grades. Researchers discovered that students with the most absences have significantly lower grades than those with few absences.
What type of study is this? If experimental study what is the IV and DV and if correlational study is it a positive correlation or negative?
Correlational study
Negative correlation because the more absences the student has the lower the grade
A business wants to determine if giving employees more control over how to do their work leads to increased job satisfaction. One group of workers is given a great deal of input in how they perform their work, while the other group is not.
What type of study is this? If experimental study what is the IV and DV and if correlational study is it a positive correlation or negative?
Experimental Study
IV-amount of input the workers have over their work
DV- Increased Job satisfaction
