Medical Experiments
Hindsight Bias
Tendency to believe, after learning outcome, that one wpuld have forseen it
Medical Experiments
Science Attitude
Curious, Skeptical, Humble
Medical Experiments
Types of Experiements
- Case Studies: 1 case to learn about a rare thing
- Naturalistic Observation: Describe behavior without explination
- Hawthorne Effect: Ppl act different when being observed
- Survey: Lots of data in short time and need to have representative group
Correlation
What is it?
- Extent to which two factors change together
Correlation
Illusory Correlation
Percieved non-existent correlation
Correlation
Regression Toward Mean
Uncontrollable events correlate with actions
Medical Experiments
What is Experimentation
- Investigator that manipulates factors
- Control and Experimental Groups
- Matched Pair design
- single and double blind studies
- statistics to show data as bigger deal
- standard dev: √∑dev^2/# of scores
