Chapter 2, Methodology Flashcards
What is Hindsight Bias?
The tendency for people to exaggerate how much they could have predicted the outcome after knowing that it occurred
What is a Theory?
An organized set of principles that can be used to explain observed phenomena
What is a Hypothesis?
A testable statement or idea about the relationship between two or more variables
Operational Definition?
The precise specification of how variables are measured or manipulated.
What is the Observational Method?
Focused on Description - What is the nature of the phenomenon?
What is Correlational Method?
Focused on Description - What is the relation between variable X and variable Y?
What is the Experimental Method?
Focused on Causality - Is variable X a cause of variable Y?
What is the definition of the Observational Method?
The technique whereby a researcher observes people and systematically records measurements of their behavior
- Ethnography
- Archival Analysis
What is Ethnography?
The method by which researchers attempt to understand a group or culture by observing it from the inside without imposing any preconceived notions they may have
What is Archival Analysis?
A form of the observational method whereby the researcher examines the accumulated documents, or archives of a culture
What is the definition of the Correlational Method?
The technique whereby researchers systematically measure two or more variables and assess the relationship between them
-Surveys
What is a Correlation Coefficient?
A statistic that assesses how well you can predict one variable based on another
This is expressed as numbers that can range from -1.00 to +1.00.
- A correlation of +1.00 means that two variables are perfectly correlated in a positive direction.
- A negative correlation means that increases in the value of one variable are associated with decreases in the value of the other.
- Finally, a correlation of zero means that two variables are not related
What is a Survey?
Research in which a representative sample of people are asked questions about their attitudes or behavior
What is Random Selection?
A way of ensuring that a sample of people is representative of a population, by giving everyone in the population an equal chance of being selected for the sample
What are the limits of the Correlational Method?
It only shows that variables are related not that it is a causation
What is the definition of the Experimental Method?
The method in which the researcher randomly assigns participants to different conditions and ensures that these conditions are identical except for the independent variable.
