Unit 0: Research Terminology Flashcards
Hindsight bias
” I know it all along” phenomenon; tendency to perceive events as being extremely predictable
Overconfidence
idea that people are more confident in their knowledge/abilities than they should be as this faulty thinking can lead to more mistakes in judgement
Theory

Hypothesis
a testable prediction often implied by a theory
Operational Definition
(know this guaranteed to be on the AAQ) a statement of the procedure used to specifically define research variables (specific measurement; using numbers) used for replication (each step os clearly stated in order to replicate)
Independent Variable
the experimental factor that is manipulated; that is the variable being studied
Dependent Variable
the experimental facto that is being measured; this may change depending on the manipulation in the independent variable
Confounding Variables
any difference between the control condition and the experimental condition other than the independent variable that affects the result
Quantitative Measures
using statistics such as the Likert Scale (survey ratings in a scale of 1-5 or 1-10) or answers from “strongly agree” to “strongly disagree:”
Qualitative Measures
allows the researcher to describe traits or characteristics in depth such as structured interview and/or case studies
Sample (Qualitative Measures)
the group that the researcher actually studies, usually smaller than the population
Population (Qualitative Measures-Sample)
the group that the researcher wants to know about
Random Selection (Qualitative Measures-Sample)
process of choosing a sample that guarantees every member of a population has an equal chance of being picked to participate, results in a random sample
Representative Sample (Qualitative Measures-Sample)
a sample that matches the larger population in terms of ethnicity, gender, race, etc.” found using random selection
Sampling Bias (Qualitative Measures-Sample)
when a sample does not represent the overall population, giving an unreliable result
