Chapter 2 - Research Methods Flashcards
erroneous belief that you knew something all along after an event has occured
hindsight bias
form of overconfidence
tendency to overestimate extent to which others share personal beliefs or behaviors
false consensus effect
describes a belief that requires people to accept information as irrefutible and to refrain from questioning authority
dogmatism
rules or techniques that provide a framework for observations
methods
objective statements made using direct observations
facts
ideas that help explain existing facts
theories
predictions about new facts, based on existing theories
hypotheses
person who takes part in an experiement who is seemingly a subject but is really working with the reasearcher
confederate
variable that a researcher can manipulate
independent variable
study in which different groups are exposed to different independent variables
between-group experiement
study in which each participant is exposed to several different independent variables
within-subject experiement
group that is subject to an independent variable
experiemental group
group that is given no treatment or who are given treatment that should have no effect
control group
process by which participants in an experiement are randomly placed into groups
random assignment
group of participants in an experiment that is identical to at least one other group in terms of a particular variable
matched sample
set of participants, one from one group, one from another, who are identical in terms of a particular variable
matched pair
situation in which an observer expects a certain behavior and only notices actions that support that behavior
observer bias, observer expectancy effect
study of people and animals in their own environment
naturalistic observation
observers who do not know what the research is about and thus are not subject to observer bias
blind observers
in depth study of one or a few individuals
case study
study of people or animals in a controlled setting
laboratory observation
technique in which the participants of a survey are chosen randomly so as to get a fair representation of a population
random sampling
series if questions about a person’s behavior or opinion in the form of a questionairre or interview
survey
form of data collection in which people are asked to describe their own behavior or mental state
self-report method
form of data collection in which people provide oral descriptions of themselves; could be strictly structured or conversational
interview
series of questions with a strict purpose that has been developed using careful controls such as precise wording, carefully constructed questions, and random sampling
questionairre
type of observational method in which participants are provided with stimuli or problems and researchers collect data about how they perform a certain task
testing
process of observing and recording a subject’s behavior
observational method
statistics researchers use to summarize data sets
descriptive statistics
statistics that use probability laws to predict how likely it is that observed results apply to a broader population
inferential statistics
three most typical scores in a set of data; mean, median, mode
measures of central tendency
