Research & Psychology
- Hypothesis: testable prediction with clear variables
- Research method: best
test's the hypothesis
- Ex. Experiments, case
studies, or observation
- Collect Data by Interview, questionnaire,
psychological tests, observation
- Analyse Data with statistics to prove/disprove hypothesis
- Write a summary of the findings
- Evaluating research by conducting more experiments (replication)
- Evaluating research by conducting more experiments (replication)
- Write a summary of the findings
- Analyse Data with statistics to prove/disprove hypothesis
- Ex. Experiments, case
studies, or observation
- Inferential Statistics: Evaluate with probability if results are due to chance
- Research method: best
test's the hypothesis
- Variables
- Independant: variable that experimenter controls
- Extraneous: variable that not under
experimenter control & can affect
dependent variable
- Ex. Personality
- Confounding variables: Conflicting variables that are difficult to sort out effects
- Ex. Personality
- Independant: variable that experimenter controls
- Scientific Approach
- Clarity & precision
- Intonate of error
- More accurate and dependable
with further testing of why
- More accurate and dependable
with further testing of why
- Clarity & precision
- Groups
- Experimental group: exposed to the
change in the independent variable
- Placebo Effect: Fake treatment but think they had treatment
- Placebo Effect: Fake treatment but think they had treatment
- Control Group: Under normal exposure to independent variable
- Sampling bias: replicating a smaller group in
the experiment with similar generalizations
- Experimental group: exposed to the
change in the independent variable
- Types of Research
- Experimental
- Controlled conditions: Isolates the relationship
with the independent & dependent variable
- May use Field study to encourage generalizability
- May use Field study to encourage generalizability
- Disadvantages: Manipulations of variables
may be impossible & most experiments
are artificial
- Controlled conditions: Isolates the relationship
with the independent & dependent variable
- Naturalistic Observation
- Observe behaviour without interfering
- Less Artificial
- Less Artificial
- Presence of an observer may change behaviour
- Observe behaviour without interfering
- Case Studies
- Study a small group
- Ideal for difficulty getting subjects
- Ideal for difficulty getting subjects
- Poor representative of the
whole population
- Study a small group
- Surveys
- Interview to get data
- Good to study behaviour thats hard to directly
- Good for attitudes opinions
on large populations
- Although, wishful thinking,
memory lapses & poorly worded
answers may occur
- Interview to get data
- Experimental
- Descriptive statistics: organize & summarize data
- Central tendency measures: median mean & mode
- Variability : difference between
control & experimental group
numbers
- Correlation: when 2 variables affect each other
- Variability : difference between
control & experimental group
numbers
- Central tendency measures: median mean & mode
