Mais conteúdo relacionado Semelhante a Research question (20) Research question1. The Research Question
Presents the idea that will be studied
Also called the “problem statement”
Research questions focus on:
Specifying the population being studied
Describing variables
Examining testable relationships among variables

2. Study Purpose, Aims, or
Objectives
Purpose
Overall goal that the research can achieve
Suggests the level of evidence to be obtained
Aims
How this particular project will achieve the goal

3. Research Questions Should:
Arise from the systematic review
Define specific question area
Fill a gap or clarify a conflict in the literature?

4. Variables
Come from the literature
Come from theoretical framework
Something that varies
Age, weight, height, religion, ethnicity
Can be observed, measured, and analyzed.
One variable influences another variable
Is X related to Y?
What is the effect of X on Y?

5. Variables
Independent variable—X—
Comes from the theory
Manipulated
Controlled
Dependent variable—Y
Outcome within the population
Varies depending on X
Observed
This is the variable we are interested in promoting or
causing

6. Population
Must be clearly specified
The setting is also usually clearly described
Breast cancer survivors who have completed
treatment

7. Developing a Clinical Question
Clinical questions have four components:
Population
Intervention
Comparison
Outcome
PICO

8. Critiquing the Research Question
Is the population being studied described?
Is there an implied relationship between two or
more variables? Between an independent (X) and
dependent (Y) variable?
Can the implied relationships be tested?

9. Critiquing the Hypothesis
Might not be explicitly stated—you may have
to infer it
Even if stated it should be reexamined in the
Results or Discussion sections
Data analysis should answer the hypothesis
The hypothesis should logically follow from
the literature review and theoretical
framework
