research designs (how do we generate knowledge) Flashcards
what are the qualitative research designs
1.descriptive
2. survey
3. correlational
4.experimental
5. quasi-experimental
what is the purpose of descriptive research
understand phenomenon, situation, or population without manipulation of variables
what are the characteristics of descriptive research
-observe and measure variables to investigate
-identify characteristics, categories and trends
-understand human behaviour
what is the purpose of survey research
measure thoughts, perceptions, attitudes, personality, emotions and behaviours
what are the characteristics of survey
-self-reported by participants
-susceptible to response biases
what are the types of surveys
1.cross-sectional
2.longitudinal
what is a cross-sectional survey
study at one point in time
-small sample from larger population
-measure opinion in one particular situation
what is a longitudinal survey
study conducted at various durations over extended period of time
what are the types of longitudinal survey and what are they
trend survey
-understand how responses change overtime
panel survey
-same group of people over years
cohort survey
-specific categories of people
what is the purpose of correlational research
identify relationships between 2 variables with no influence from extraneous variable
what are the characteristics of correlational
- non-experimental
-recognize patterns and trends in feedback gathered
what are the types of correlation and what are they
positive correlation
-both variables change in the same direction
negative correlation
-variables change iin opposite direction
zero correlation
-no relationship between the variables
what is the purpose of experimental research
measure effect of one or more independent variable on one or more dependent variable
what are the characteristics of experimental
-only research design that allows for causal inferences to be made
-conduct set of procedures to test hypothesis
-variables are manipulated by researcher
-random assignment of intervention
-result of intervention measured
purpose of quasi-experimental research
identify cause and effect relationship between independent and dependent variable
