Research Approaches Flashcards
Quantitative Research purpose
To answer questions with numerical, quantifiable elements
Demonstrate an association or relationship between variables
Can quantitative research capture ALL the variables
Probably Not
Two main types of quantitative studies
Experimental
- Used to determine if an intervention is beneficial
When something is implemented OR manipulated
MAIN THING: There is an independent variable used (the intervention)
Control group and Dependent variable
Non experimental study
Does not have intervention
Can be reflected as PIO question
Used to describe relationship bw two or more variables
Where can you find the aim of the paper
Under the purpose (abstract), or right before the methods
Do all studies have hypothesises?
No, sometimes will be seen in a quant. but most often in a randomized control trial
A prediction, including the variables
Two types of quant. research
Experimental Desifns
Non Experimental
The strongest type of quant method
Expeirmimental design
No randomization
Know the quant vs qual chart
Why are randomized control trials used
To demonstrate the effectiveness of a thereapeutic intervention or causality
What do randomized control trials use
Control group (determine the effect of the intervention)
Intervention group
Uses clinical (BP, weight, height etc) and non-clinical (QOL questionnaires, patient satisfaction etc)
Indpendent variable
Variable beleifed to cause or influence the dependent variable in experimental research
Intervention under study
Specific characteristics that make a RCT
Intervention
Control Group
Randomization (Does researcher randomly allocate the participants to either the intervention group or the g=control group)
Randomization achieves
Making sure both groups are starting from the same baseline
Quasi-experimental design
Not ‘true’ experimental designs
No randomization
No control group
No pre test only post test
