Research Design - Part I
This is the extremely important lesson to final year project students.
Above diagram displays that in the research design for the final year project.
- We need to clearly describe the research plan and identify what are the impact of the project plan.
- After identifying the requirements of the project need look at the objectives of that and what are the actually achieved from the project.
- Then identified how to solve the problems.
- Finally primary and secondary research about the project.
Example 1: Sathutu Uyana booking system.
Example 2: You were selected to the Ceylon Electricity Board as a project manager. You need to solve some problems in the that organization. From the beginning you don't know anything about CEB. But you might know what is the procedure in Sathutu Uyana.
Research include both primary research that you do and secondary research that you do.
Primary Research.
Primary research is the research what you to and collect the information.
ex: Interviews.
Documentation.
Questioners.
Secondary Research.
Research that some one has done before is the secondary research.
Literature review will fall into that category.
Processes Involved in Research Design.
- At the end of the project what are you going to achieve.
- Deliver documentation and system of the project.
- Literature review - What are the other things that identified in the project.
- Selected data collection methods.
- Selected sampling methods.
ex: Identify the average of a APIIT student is 20 years old.
We can get a snap shot to represent sample.
Get that part and represent it.
Need to get a snap shot of all the batches.
Sample can be generate to the entire batch.
- Identify the sampling size.
- Identify the sampling methods.
Sample size is equal to population size then it is senses.
If the sample size is large, it's hard to identify the general population.
Sampling Techniques.
There are two types of sampling techniques.
Probabilistic Sampling.
It means that everyone in the population should have equal change of getting selected to this sampling method. There are two tasks that looking in this sample techniques to complete it.
--> If everyone is there.
--> List of the entire population.
Systematic Sampling.
- According to the above APIIT students example here we can use every fourth student who walks in to APIIT.
Simple Random Sampling.
- List of the population.
- Utilize the random number table.
- Reduce personal preferences from the research side.
Cluster Sampling.
- Divided your population in to clusters (groups).
- Cluster it based on gender.
- Can have a cluster in side one cluster
ex: Colombo 6, Colombo 7
- Cluster also based on the age.
Stratified Sampling.
- Different groups.
- Divided in the groups and select the particular group and that is a sample.
Non - Probabilistic Sampling.
Non - Probabilistic Sampling doesn't make sure that every one in the population is no equal to the chance of getting selected to the sample method.
Convenient Sampling.
- In the convenient sampling generalization is the problem.
ex: Snow ball sampling.
6. Selected data analysis methods.
- Utilize research tools.
- Observations.
- Interviews.
- Questioners.
- Document reviews.
- Use of the research tools that can collect the data.
Types of Researches.
- Servery.
- Case study.
- Action research.
- Experimentation.
- Ethnography.
- Longitudinal.
- Interviews.
- Document review.
- Case study.
- Action research.
- Experiments.
- We can you any of above research types for the researches.
7. Rationale for
selected technical aspects.
8. Selected Design
approach.
9. Timelines.
Learning gain of the Lecture.
Learned the process about how to research. Identify what are the primary research, secondary research, and the processes involved research design including the sampling techniques and other research tools.
Personal Opinion.
Important lecture for us. It helps to final year project search.
