criteria for whether a subject is scientific
features of science - objectivity
researchers remain unbiased in their work
‘psychology meets this sometimes’
all sources of bias are minimised
some methods more objective than others eg. brain scans
eg. thematic analysis, case studies are subjective!
features of science - testing theoretical predictions
‘psychology does meet this’
theory - general laws that allow us to explain certain behaviours
theory construction - gathering evidence by directly observing + testing theories and proving or disproving predictions objectively
features of science - testing theoretical predictions
why is it important to test a hypothesis
all research begins with a hypothesis
results mean you accept or reject the hypothesis
if your results support the hypothesis then you can use this evidence to support your theory construction
features of science - falsifiability
features of science - paradigms
3 distinct stages of development of a science:
features of science - replicability
nominal data
data divided into categories
known as discrete data - Ps can only be put in 1 category
- gives researcher little detail
ordinal data
data that has been ordered eg. ranked
- subjective and doesn’t have equal intervals
- not precise
interval data
based on numerical scales in which the intervals are universal
each interval is precise eg, cm, weight
