A whole lot of reading is required at this stage. A properly made literature survey will help you a lot in understanding and dealing with the problem in a better manner.

The next step is to make a proper and scientific sampling. A scientific sample has following qualities:

1) Representativeness- An ideal sample must be such that it represents adequately the whole data. We should select those units which have the same set of qualities and features as are found in the whole data. It should not lack in a quality found in the whole data.

2) Independence- The second features of a sample is independence that is interchangeability of units. Every unit should be free to be included in the sample.

3) Adequacy- The number of units included in a sample should be sufficient to enable derivation of conclusions applicable to the whole data. A sample having 10% of the whole data is adequate but if it has only 1 or 2% it is not adequate.

From a given data the choice of sample is made by various methods. Which method will suit in a given problem will depend upon its nature, scope and investigator.

1) Deliberate or purposive sampling- In this method the investigator has complete freedom in choosing his sample according to his wishes and desires. The investigator chooses certain items from the whole data and studies them only. To choose or leave an item for the purpose of study depends entirely upon the wishes of an investigator and he will choose those items or units in his judgments as are representative of the whole data.

There are other methods of sampling also. The next step is the collection of information. The sources of information may be classified into primary sources and secondary sources. Primary sources include the actual information received from the individuals directly concerned with the problem of study. The secondary sources of information include all types of published and unpublished, public or private documents and other such types of information.
