- Scientific inquiry fixes confidence
- Curiosity, skepticism, & humility make science possible
Scientific Method:
- Theory linked with observation
- Theory: Organizes, observes & predicts behaviors
- Hypothesis: testable predictions produced by “good” theories
- Operational definition: statements of procedures used to define research variables
↳helps replicate studies with precise predictions that are testable
- Confounding variables: anything that could impact the dependent variable that is not due to the
independent variable
-Random sampling: Everyone has an equal chance of participation
↳Makes results unbiased
-Wording effect: Different wording holds different impacts on people
-Case study: observe technique - one person studied in depth to reveal universal principles
-Naturalistic observation: Watching the subject in the natural environment
Correlation:
↳How one trait is related to another
↳Correlation coefficient: ( ranges from -1 ± 1)
↳Association DOES NOT EQUAL causation
-Illusory correlation: Non-existent trend can have an association - think dangers of bread
-Standard Deviation:
↳A measure of dispersion that shows the spread of scores around the mean
