Research Designs Flashcards
Carries out experiment in a controlled fashion soo precision is maximised
Experimental
Establishes effect independent variable has on dependent variable
Experimental
Research that lacks manipulation of variables
Non-experimental
Researchers monitor participants and record notes on their behaviour
Observational
In depth investigation of an individual, group of people or single event, large amount of data collected
Case-study
Measures linear relationship between two variables
Correlational
Repeated observation of the same variables
Longitudinal
Studies data at a single point in time, participants selected based on particular variables of interest
Cross sectional
Strengths: controls variables, establish cause and effect relationships
Experimental
Strengths: no need to control conditions, allows to research things if manipulated may be unethical
Non-experimental
Strengths: can be replicated by other researchers, participants more likely to behave naturally
Observational
Strengths: detailed info collected, info from multiple POV’s
Case-study
Strengths: hypothesis can be based on correlation for an experimental design, can be used when manipulated variables is unethical
Correlational
Strengths: allows examination of changes and development, info on casual relationships, predicts outcomes early, provide rich data
Longitudinal
Cons: reduced authenticity, human error potential
Experimental
Cons: cannot identify cause and effect relationships, require larger sample size
Non-experimental
Cons: researcher bias potential, participants behaviour may not be normal if they know they’re being observed, ethical guidelines can be broken
Observational
Cons: no generalisation in population, limited info due to no control group
Case-study
Cons: do not show cause and effect only relationships, Correlational can be from other extraneous variables
Correlational
Cons: time consuming and expensive, loss of participants, threats to validity, ethical considerations
Longitudinal
Cons: cannot establish causal relationships, cannot examine changes over time, may not be suitable for studying rare conditions
Cross sectional
