Lecture 2: quantitative Flashcards
what is the goal of quantitative research?
explains the relationships between variables while predicting an outcome from those relationships
what are the types of quantitative research?
1) experimental
2) quasi-experimental
3) correlational
4) descriptive
why does a descriptive research entail less control?
the factors and natural setting are already in place and the only thing that needs to be done is to observe the progression of the relationship between the subject and variables
what does descriptive research entail?
discovery of new meaning, along with description and exploration of phenomena in real-life situations
what does correlational research present?
the type and strength of the relationship between two or more variables
no cause and effect
what does quasi-experimental research present?
cause and effect relationships between variables
why is quasi-experimental research not ideal for settings that are nonpractical and one with ethical implications?
it examines human behavior
what is the most common scenario where quasi-experimental is used?
implementing treatments and examining the relationship between the outcome and intervention
define applied research
practical research derived from scientific evidence that will directly influence clinical practice
define rigor
striving for excellence in research, making the study credible
define control
it is the imposing of rules to decrease possibility of error and increase accuracy of findings
define basic research
pure research that is only involved in the lab
what does applied research entail?
1) problem solving in clinical practice
2) studies the effects of an intervention
3) applies findings on real patients
define extraneous variables
variables that can get in the way between the independent and dependent (based on hypothesized relationships)
also called confounding variable
what are the types of settings for quantitative research?
1) natural/ field (home, playground)
2) partially controlled (community clinics)
3) highly controlled/ lab (research unit, lab, ICU)
