1. Research purpose
Outline
• Definition of research purpose
• Importance of research purpose
• Qualities of specific purpose
![Page 3: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/3.jpg)
Definition and importance
• It is a description of what is to be achieved by
the study.
• It summarizes the overall study goal
• It identifies the key study variables and their
possible interrelationships, as well as
identifies the the study group or population.
![Page 4: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/4.jpg)
Qualities of Research purposes
Research purpose should be SMART:
• Specific: Addressing one thing only
• Measurable: Use proper verbs (Determine, compare, Identify, evaluate, demonstrate , describe)
• Attainable: given the resources available
• Realistic: given the local conditions
• Time bound: can be achieved in the given time

Examples
- The purpose of this study is to determine the factors
associated with increased number of diarrhea cases
among under fives in X village
- The purpose of this study was to determine whether
viewing a video of an actual pediatric inhalation
induction would reduce the level of parental anxiety

Variables
• Variable is “any possession of a person, thing,
event, setting, and so on that is not fixed.”
• Types
1. Independent Variable
(presumed cause)
2. Dependent Variable
(presumed effect)
![Page 8: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/8.jpg)

Variables
–The Independent Variable: This Is The
Variable That Determines, Influences, Or
Produces The Change In The Other Main
Variable
–The Dependent variable: This variable is
dependent on or influenced by th4e
independent variable(s)
![Page 9: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/9.jpg)
Research question definition
• It is an interrogative statement that direct
interpretations of research purpose.
• It is the specific inquiry researchers want to
answer in addressing the research problem.
![Page 10: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/10.jpg)
1. F – Feasible2. I – Interesting3. N – Novel4. E – Ethical5. R – Relevant
Using FINER, you should be able identify or frame an actual research question.
Qualities of a Good Question

Types of questions
Types of Questions
Descriptive questions
Correlationquestions

Descriptive research questions
• Focused on describing characteristics of a population.
Examples:• What is the main factor for social media
addiction among teenagers?• What percentage of women breastfeed their
infants?
![Page 13: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/13.jpg)
Correlation research question
• Focused on asking questions about
relationships between variables
• Normally looks at associative statistics
Examples:
• Are teenagers who spend more time on social
media spending less time on studies?

Research hypothesis
![Page 15: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/15.jpg)
Definition of Hypothesis
• It is a prediction about the relationship
between two or more variables
• It is a declarative statements
Remember…you are always testing to see
if the Independent Variable has an effect
on the Dependent Variable.
![Page 16: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/16.jpg)
Types of Hypotheses
Alternative hypotheses
Null hypotheses
are statements of expected relationships between variables
![Page 17: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/17.jpg)
Types of Hypotheses
Null hypotheses (statistical hypotheses)
They state that there is no relationship
between the independent and dependent
variables.
For examples, patients’ age is unrelated to
their risk of falling
![Page 18: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/18.jpg)
Types of Hypotheses
Alternative hypotheses (research hypotheses)
They are statements of expected relationships
between variables
Ex. Younger patients tend to be less at risk of a fall
than older patients
The risk of falling increases with the age of the
patient
![Page 19: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/19.jpg)
Characteristics of a good hypothesis
1. Testable
2. Logical
3. Hypotheses should be expressed in the
present tense.
4. States relationship between variables
A hypothesis is composed of an independent variable
(cause) and a dependent variable (effect)

Examples of research study
• The research title
The effect of using simulation based learning
versus traditional learning on nursing students'
clinical performance of respiratory system
assessment
![Page 21: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/21.jpg)
Examples of research study
• The research purpose
This study aimed to compare the effect of using
simulation based learning versus traditional
learning on nursing students' clinical
performance regarding respiratory system
assessment.
![Page 22: Lecture Title Lecturer Name year Subject Name Code.](https://reader035.fdocuments.in/reader035/viewer/2022062315/5697bfcf1a28abf838caa1aa/html5/thumbnails/22.jpg)
Examples of research study
• Research hypotheses
1. Students who attend simulation based learning
exhibit a higher score in knowledge test than those
who attend traditional learning.
2. Students who attend simulation based learning
exhibit a higher performance score of respiratory
assessment than those who attend traditional
learning.
