4. Why We Need Research Objectives??
5/24/20244
Research objectives will help the researcher to:
1.Focus
2.Avoid
3.Organize
4.Directions

5. Characteristics of Research Objectives
5/24/20245
SMART:
Specific
Measurable
Attainable
Realistic
Time-bound

6. Characteristics of Research Objectives
5/24/20246
Research objective should be:
Relevant
Feasible
Logical
Observable
Unequivocal

9. Stating the objectives
5/24/20249
The objectives should be presented briefly and concisely.
Objectives must be in concurrence with research
problem and must be stated in coherent way and in
a logical sequence.
The objectives are clearly phrased in operational
terms, specifying exactly what researcher is going
to do, where, and for what purpose.
Use action verbs those are specific enough to be
evaluated.

1.Identify
2.Assess
3.Find out
4.Describe

12. VARIABLES
5/24/202412
Anything which vary!!
E.g.
1.weight,
2.height,
3.Hb,
4.BP,
5.pulse etc.

13. Types of Variables
5/24/202413
Dependent variable: Outcome/ criterion variable:
observational study
Independent variable:
Manipulated variable/ Treatment variable
Predictor variable: in observational study

14. Dependent variable & Independent
variable
5/24/202414
For example,
a researcher is observing effect of ginger intake (independent
variable) on morning sickness symptoms (dependent
variable) among pregnant women.

15. Types of Variables
5/24/202415
Confounding variable/Extraneous variables
Intervening/ Mediating/Moderating variable/ Control variable.

17. Types of Variables
5/24/202417
Research variable: (Descriptive, exploratory, comparative, and
qualitative research studies)
Demographic variable: Age, gender, educational status,
religion, social class, marital status, habitat

18. Research variable
5/24/202418
Example:
‘An exploratory study on factors contributing to sleep
disturbance among patients admitted in selected
intensive care units of AIIMS, New Delhi’.

19. Miscellaneous variables
5/24/202419
Latentvariable:Anabstractvariablewhichcannotbe
directlyobserved/measuredwithoutconvertingtheminto
manifestvariable(concreteconcepts)
Univariate study
Bivariate study
Multivariate study

20. Miscellaneous variables
5/24/202420
Manifest variable/ Indicator variable:
A concrete variable, which can be observed/ measured
assuming it indicate presence of latent variable.
Intelligence is a latent variable, whereas IQ test
score, writing or reading ability are manifest
variable.
