Quantitative
Put the hierarchy of evidence in order: Case control Cohort Systematic reviews Case series - case reports RCT ideas,opinions Cross-sectional studies
Systematic RCT cohort Case control Cross sectional Case series case reports Ideas, opinions
Which type of evidence has a high chance if bias/errors
Expert opinion
Are case series - case reports observational or descriptive
Descriptive

RCT
Null hypothesis testing is:
a. Where a statement is made about no variation between groups
b. Where a statement is made about no relationship between groups
c. Where a statement is made about no effect between groups
d. Where a statement is made about no difference between groups
No difference between groups
In quantitative research terms, an AIM is:
a. The breakdown of the research detail
b. A statement about the relationship between the relationship variables
c. The broad statement of what is intended
d. A calibration that allows accurate measurement
The broad statement
The study sample is:
a. Patients drawn from the study population
b. Patents who meet the exclusion criteria
c. Patients who are more likely to give better outcomes
d. Patients who meet the inclusion and exclusion criteria
Patients from the study population
The main reason for using randomisation to allocate patients in a controlled trial is:
a. Make the allocation fair to patients
b. Balance the groups by specific criteria
c. Prevent certain types of bias
d. Allow for comparison within groups
Prevent certain types of bias
A method of allocation LEAST LIKELY to achieve balance of important patient characteristics between groups to use:
a. Minimisation
b. Simple randomisation
c. Block randomisation
d. Stratification with block randomisation
Simple randomisation
The dependent variable is the
Outcome of interest
The independent variable is the
Intervention factor
