Measurements
Defining them
Coding
Familiarisation of data
12
What is one of the main functions of evidencebased practice in terms of the NMC standards regarding fitness to practice?
Evidence-based practice ensures clinical guidelines are followed
Evidence-based practice stops development of researchers of the future
Evidence-based practice ensures practice remains current
Evidence-based practice ensures patients aren't involved in decision-making
13
What are the key features of a survey design? (pick two answers)
to allow the analysis of only dependent variables
distribution and interrelationships of variables
High participation numbers, aims to not answer question on prevalence
High participation numbers, ims to answer questions on prevalence,
14
Why might data from qualitative research be considered less important than data from randomised controlled trials?
The findings from qualitative research are not usually generalizable
The findings from qualitative research based on interview data
The findings from qualitative research generally lack rigour
The findings from qualitative research are not methodologically robust
15
What is the main purpose of random allocation?
To ensure the sample size is equal between groups
To ensure the study is reliable
To promote internal and externalvalidity
To ensure the study is double blinded
16
How is clinical significance established at the outset of a research study?
By ensuring a sufficiently large sample can be recruited
By determining the minimum important difference that needs to be observe
By agreeing the level of the p-value to be used when analysing the results
By ensuring all patients can be followed up
17
What is the most likely consequence of implementing evidence-based practice?
Healthcare decisions will be based on the highest quality of research
Highest quality of care & best possible outcomes are likely to be achieved
There will be no variation in the care given to patients
Patients and their families will always be involved with the decisions made
18
What type of clinical question would best be answered by interpretative/qualitative research designs?
