6. 6
Course assignment:
Develop a research project
Learn the general steps in the research process
from research idea to project implementation
Identify a research problem
Define research questions, directional and non-
directional hypotheses
Identify the best possible research design for your
hypotheses
7. 7
Research Defined
Research is an organized and
systematic way to find answers to
questions
Research is a creative process
8. 8
Why is research important to
medicine and public health?
Knowledge obtained from sound
research is transformed into clinical
practice, leading to medical practice
that is evidence-based.
9. 9

12. 12
A Research Question Must
Identify
1. The variables under study
2. The population being studied
3. The testability of the question
13. 13
Variables in research
Have 2 or more properties or qualities
Age, sex, weight, height
Is one variable related to another?
“ Is X related to Y? What is the effect of X on Y?” etc.
14. 14
Variables in research
Independent
variable:
has a presumed effect
on the dependent
variable (outcome)
May or may not be
manipulated
Dependent variable:
Something that varies
with a change in the
independent variable
Outcome variable
15. 15
Hypothesis
Statement about the relationship
between 2 or more variables
Converts the question into a statement
that predicts an expected outcome
A unit or subset of the research
problem
16. 16
Characteristics of hypotheses
Declarative statement that identifies the
predicted relationship between 2 or
more variables
Testability
Based on sound scientific
theory/rationale
17. 17
Directional vs. Non-Directional
Hypotheses
Directional hypothesis
Specifies the direction of the relationship
between independent and dependent
variables
Non-directional hypothesis
Shows the existence of a relationship
between variables but no direction is specified
19. Prepare PowerPoint
presentaiton
10 minutes long
~10 slides
Select 1 presenter from each group
Present during the last day
Each presentation should include
research area, significance, hypothesis,
and rough design of the experiment
20. Practical applications of this
project?
Create your own research project
Understand published research papers
Understand presentations at scientific
conferences
Publish your research!!
