Chapter Two: Methodology Flashcards
Hindsight Bias
The tendency for people to exaggerate how much they could have predicted the outcome after knowing that it occurred
Theory
An organized set of principles that can be used to explain observed phenomena
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
Observational Method
The technique whereby a researcher observes people and systematically records measurements of their behaviour
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 might have
Interjudge Reliability
The level of agreement between two or more people who independently observe and code a set of date; by showing that two or more judges independently come up with the same observations, researchers ensure that the observations are not the subjective impressions of one individual
Archival Analysis
A form of the observational method whereby the researcher examines the accumulated documents, or archives, of a culture (ex. Diaries, novels, magazines, newspapers…)
Correlational Method
The technique whereby researchers systemically measure two or more variables and assess the relation between them (ex. How much one can be predicted from the other)
Correlation Coefficient
A statistic that assesses how well you can predict one variable based on another (ex. How well you can predict people’s weight from their height)
Surveys
Research in which a representative sample of people are asked questions about their attitudes or behaviour
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
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 (The one thought to have a causal effect on people’s responses)
Independent Variable
The variable a researcher changes or varies to see if it has an effect on some other variable
Dependent Variable
The variable a researcher measures to see if it is influenced by the independent variable; the researcher hypothesizes that the dependent variable will be influenced by the level of the independent variable
