Research Methods- Experiments, Observations Flashcards
Strength of Laboratory experiment
-Extraneous variables decreases since high in controls
-can establish cause and effect
-increases internal reliability (easily replicable)
Weakness of Laboratory experiment
-Low in ecological validity due to control
-the risk of demand characteristics
-ethical concerns
Strength of Field experiment
-High in ecological validity
-no risk of demand characteristics
Weakness of Field experiment
-Extraneous variables reduce cause and effect to be established
-ethical concerns
Strength of Quasi-experiment
-Gives the ability to look into things that may be difficult to gain content into
-naturally occurring IV
-highly controls so easily established cause and effect
Weakness of Quasi-experiment
-Low in Ecological validity
-ethical concerns
Ecological validity
-high
-low
a measure of how true to life experiment is
high-realistic conditions
low-control/ artificial/ unrealistic conditions
Name 4 research methods
experiments, observations, self reports, correlations
Name the data types:
Primary data- self
Secondary data- else
Quantitive- numbers
Qualitative- literacy
Longitudinal study
Data is developed over a long period of time to track developments in behaviour
Snapshot
Data found at one single point in time
Sample
portion that is most representative of the target population
Name all ethical issues
Informed consent, confidentiality, right to width-draw, protection of participants, deception, debriefing is a way to solve
What are the types of hypothesis
Alternate:
-one tailed/ directional (significant incr or decr) and two tailed/ non directional (a change but not specified)
Null:
-no significant difference
