Accepting something is true
simply because someone in a
position of authority says it is -
e.g parents, lecturers
Pure Reason
It is the way it is because it logically
must be that way - a priori - truth
arrived at by logic and reason -
advantages - laws and social
contracts do not stem from
empirical reason - disadvantages -
inability to resolve arguments
when they occur
The Scientific
Method
Conclusions
should be based
on evidence which
is empirical and
objective
How is the
scientific
method
applied?
Induction
Evidence is gathered
from multiple
observations - but
how can a finite
number of
observations
guarantee what will
happen in the future?
Falsifiability - Karl
Popper
For a theory to be scientific, it must be falsifiable -
if evidence contradicts theory, we formulate a
new one, if evidence supports it, we regard it as
undefeated - but how do you determine whether
a theory should be accepted as true?
Bayesianism
Belief comes in degrees - the likelihood of future
events can be expressed on the basis of past
knowledge - e.g it is likely 90% of students will
pass research methods - revise probability
predictions when faced with ned evidence in
support or against - key principle in statistics
Hypothetico-Deductive
Method
Theory
Hypotheses
Empirical tests
Results
Theory either
undefeated or needs
refining/abaondoning
Focus on describing,
predicting & identifying
causes - usually large
sample sizes
Qualitative
Research
Description, often text
based
Not
experimental
- focus on
underlying
meaning of
behaviours,
small samples
Descriptive vs relational
Descriptive - describes behaviour
or phenomena but can't make
predictions or imply causality
Relational -
explores
relationship
between two or
more behaviour or
phenomena - able
to make
predictions but still
not causality
Experimental research
Manipulation of one or more
variables in order to measure the
effect on another variable -
determines if any differences arise as
a direct result of the manipulation
Causality can be
inferred because we
have controlled all
other variables
Relational - X is related to Y
Experimental - X is responsible for Y
Triangulation
Methodological Pluralism -
using multiple methods
Methodological Triangulation -
convergence of the findings of
methodologically varying studies
can lend credence to theory pattern
