3. Experimental Research
Problem Identification
Decide on procedure / instrumentation
Measurement and data analysis
Discussion of result
Conclusion
4. CHOOSING THE MEASUREMENT
Choosing the scientific
measurements are also crucial
for getting the correct
conclusion. Some
measurements might not reflect
the real world, because they do
not measure the phenomenon
as it should
5. Experimental Testing
To be assigned a standing or
evaluations on basis of tests.
To apply a test as a means of
analysis or diagnosis
6. Experimental Design
A blueprint of the procedure that enables the
researcher to test his hypothesis by reaching valid
conclusions about relationships between
independent and dependent variables.
It refers to the conceptual framework within which
the experiment is conducted.
An efficient procedure for planning experiments so
that the data obtained can be analyzed to yield valid
and objective conclusions.
The design of all information-gathering exercise
where variation is present, whether under the full
control of the experimenter or not.
7. Experimental Design
What is Experimental Design?
What are the uses of Experimental Design?
What are the steps in Experimental Design?
USE RSM: Response surface methodology
9. Good Experiment Traits….
Can produce target variables
(what precautions were taken against likely source of
noise, bias, etc?)
Able to identify limitation/ sources of errors
Time and economic costing
(is the methodology for data collection appropriate?)
Database for all measurements @ analysis
Analytical techniques
(are the techniques used for analysis appropriate? )
Reliability across time and replication
(has the best methodology been chosen? )
10. HOW AND WHEN TO DESIGN
YOUR EXPERIMENT ???
CHECK YOUR
PROBLEM
STATEMENT !!!!
11. 1. TITTLE
Potential of vermicomposts on the growth
performance of low land roses
Vermicompost it has significantly improved seed germination, enhance
seedlings growth and development and increase overall plant productivity
(Euras, 2011). It has been proven that with vermicompost not only
improves the growth of corn seedlings and yield (Atiyeh et al., 2010).
2. LITERATURE REVIEW
it also increases the number of flower
buds of low land roses?
3. PROBLEM STATEMENT
13. 1.0 Experimental site
1.1The planting site is located in the
greenhouse at UiTM Perlis. The roses will be
plant starting from August to December 2012.
2.0 Preparation of vermicompost
2.1To prepare vermicompost, cement tank of
dimension 1.8288m x 0.9144m x 0.3048m
(length x width x height) will be used as
recommended by Department of Agriculture,
Perlis.
3.0Statistical analysis
3.1Two-way analysis of variance (ANOVA) will be
used to determine any significant difference among
the parameter analyze at 0.05% level of significance.
14. CATEGORIES OF EXPERIMENTAL
DESIGN
Lab Experiment (Artificial
Environment)
Field Experiment (Natural
Environment)
15. Lab Environments (Artificial Environment)
The study of cause and effect relationship between
dependent and independent variables are clearly
defined
Other variables that can contaminates/ confound the
relationship are tightly controlled
Sometimes necessary to manipulate independent
variables to established causal
***Manipulation means creating different levels of
independent variable to assess the impact on
dependent variables.
