Readings Flashcards
statement of relations among concepts within a set of boundary assumptions and constraints. It is no more than a linguistic
device used to organize a complex empirical
world.
Theory
f preventing the observer from being dazzled by the full blown complexity of natural or concrete events
Function of theory
Purpose of theoretical statements
- to organize (parsimoniously) (karig, simpel)
- to communicate (clearly)
Features or quality of individual things, acts or events
Description (different than theories)
Three types of description
- categorisation of raw data
- categorisation of typologies
- Categorisation of metaphors
Empirically categorising things (type of description)
categorisation of raw data
Mental construct formed by the synthesis of many individual phenomena
which are arranged according to certain points of view (more abstract than categ. of raw data) (type of description
categorisation of typologies
Statement that says that two phenomena are isomorphic (have characteristics
in common)
(type of description
categorisation of metaphors
Statement of relationships between units observed or approximated in the empirical world, answers the questions how, when, why, system of constructs and variables in which the constructs are related to each other by propositions and the variables are related to each other by hypotheses, bounded by theorist’s assumptions
Theory
Constructs which by their nature can’t be observed directly
Approximated units
Variables which are empirically operationalised by measurement
observed units
Based on assumptions about value time and space (implicit values of theorist, explicit restrictions [limit theory to specific units of analysis])
boundaries of theories
Whether a theory is constructed such that empirical refutation (act of disproving or challenging) is possible, theory can’t be proven but only disproven.
falsifiability
Two primary criteria upon which any theory may be evaluated
falsifiability and utility
Usefulness of theoretical system, bridge that connects theory and research, theory is useful if it can explain and predict, often only good for prediction but does not provide explanation
Utility
Theory is useful when … : core elements of utility
- explanation
- prediction
Types of falsifiability
- falsifiability of variables
- falsifiability of constructs
- Falsifiability of relationship
Types of utility
- utility of variables and constructs
- utility of relationships
Falsifiability of variables
Measurement issues, variables must be coherent (validity, noncontinuousness,
reliability)
falsifiability of constructs
Construct validity. one can empirically differentiate the construct from other constructs that may be similar, and that one can point out what is unrelated to the
construct, construct validity can only be rejected and not confirmed.
criteria of Falsifiability of Relationships
Logical and Empirical Adequacy
Implicit or explicit logic embedded in the hypotheses and propositions which
ensures that hypotheses and propositions are capable of being disconfirmed. must be nontautological (meaningful, substantive information_ and nature of relationship between antecedent and consequent must be specified
Logical adequacy
