three moves of drafting literature review
1. establish importance of topic 2. introduce and synthesize studies 3. identify gaps - transition to rest of paper
variable
A factor that can change in an experiment
ecological fallacy
The fallacy of deducing a false relationship between the attributes or behavior of individuals based on observing that relationship for groups to which the individuals belong
causality
The notion that a change in one factor results in a corresponding change in another
deductive
a logical process in which conclusions are drawn from a set of premises containing no more info than the premises taken collectively. E.g. All dogs are animals. This is a dog; therefore this is an animal.
interval
a measure for which a one unit difference in scores is the same throughout the range of the measure
nominal
a measure for which different scores represent different but not ordered categories
ratio
a measure for which the scores posess the full mathmatical properties of the numbers assigned
ordinal
a measure for which the scores represent ordered categories that are not necessarily equidistant from one another
independant veriables
a phenomenon thought to influence, effect, or cause some other phenomenon
inductive
a reasoning process in which a conclusion is drawn from several observations
empirical generalization
a statement that summarizes the relationship between individual facts and that communicates general knowledge.
purpose of literature review
a systematic examination and interpretation of the literature for the purpose of infoming further work on the topic
interitem association
a test of the extent to which the scores of several items, each thought to measure the same concept, are the same. Results are displayed in a correlation matrix.
intervening variable
a variable coming between and independent variable and a dependent variable in an explanitory scheme
theory
an explanation using an integrated set of principles that organizes and predicts observations
antecedent variable
an independent variable that precedes other independent variables in time
empirical verification
characteristic of scientific knowledge; demonstration by means of objective observation that a statement is true
empirical
derived from experiment and observation rather than theory
normative
describes beliefs or values about how things should be or what people ought to do rather than what actually is
parsimony
if two explanations appear equally plausible, choose the simpler one.
levels of measurement
nominal, ordinal, interval, ratio
hypothesis
possible explanation for a set of observations or possible answer to a scientific question
theoretical research
research designed specifically to test some developmental explanation and expand scientific knowledge
applied research
research undertaken to solve a specific problem
types of validity
retest method, alternative form method, split-halves method
empiricism
the application of empirical methods in any art or science
validity
the correspondence between a measure and the concept it is supposed to measure
reliability
the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting
positivism
the form of empiricism that bases all knowledge on perceptual experience (not on intuition or revelation)
dependent variable
the phenomenon thought to be influenced, effected, or caused by some other phenomenon
falsifiability
the principle that a good scientific idea or theory should be capable of being shown to be false when tested using scientific methods
operational definition
the rules by which a concept is measured and scores assigned
unit of analysis
the type of actor (individual, group, institution, nation) specified in a researcher's hypothesis
operationalizing
turning abstract ideas into something measurable
