Dissertation ideas are needed to submit before you actually start your research work. The merit of your dissertation ideas will decide whether you will get permission for doing research work or not. That is the reason that you should make your research ideas with utmost care.
The proposal will describe your planned method of study in an abbreviated manner. First of all it will describe the significance of your research subject and the new dimensions those you are going to discover through it. It will describe in an abridged manner some of the sections of your proposed research paper like literature review etc.
The next important part is the research methodology section of your paper. The first item of methodology section is the sampling technique. Sometimes it is possible and practical to examine every person or item in the population we wish to describe. We call this a complete enumeration or census. We use sampling when it is not possible to count or measure every item in the population. We resort to sampling because of two primary reasons namely: Time and Cost. Other factors why we resort to sampling are because ...
... of practical problems. We use sampling in our daily lives such as: (a) When we shop we often take a sample of small piece of cheese before purchasing any, then decide from one piece what the larger chunk will taste like. (b) While cooking we sample a small spoon of the dish to check the taste of the dish giving the final ok.
If we taste all the material there will be none left. Testing the entire product often destroys it and is unnecessary. To determine the characteristics of the whole product, we have to sample only a portion of it. The word population is referring not only to people but to all items that have been chosen for study and the word sample to describe a portion chosen from the population. Mathematically, we can describe samples and populations by using measures such as the mean, median, mode and standard deviation; these terms describe the characteristics of a sample, they are called statistics. A statistic is a characteristic of a sample; a parameter is a characteristic of a population. The next important thing is the method of data collection. There are different methods for data collection like-
1) Direct Personal Interview- Here, the investigator personally comes in contact with the units. The investigator interviews or observes the units and extracts the required data from them. Since, the investigator personally collects the data, the data are reliable. The investigator, here, can use his skill in extracting accurate data from the units. He can also collect, if necessary, additional interesting information. This method is costly and time consuming. It can be used only when the number of units to be contacted is small and when they can be reached easily. In this method, there is scope for bias.
There are different other methods also for collection of primary and secondary data.
