Normally we can gather data from two sources namely primary and secondary. Data gathered through perception or questionnaire review in a characteristic setting are illustrations of data obtained in an uncontrolled situation. Secondary data is the data acquired from optional sources like magazines, books, documents, journals, reports, the web and more. The chart below describes the flow of the sources of data collection.

Primary data will be the data that you gather particularly with the end goal of your research venture. Leverage of Primary data is that it is particularly customized to your analysis needs. A drawback is that it is costly to get hold of. Primary data is otherwise called raw information; the information gathered from the first source in a controlled or an uncontrolled situation. Cases of a controlled domain are experimental studies where certain variables are being controlled by the analyst.
The source of primary data is the populace test from which you gather the information. The initial phase in the process is deciding your target populace. For instance, if you are looking into the attractiveness of another washing machine, your target populace may be newly-weds.
Clearly, it’s impracticable to gather information from everybody, so you will need to focus on the sample size and kind of sample. The specimen ought to be arbitrary and a stratified random sample is frequently sensible. In our washing machine illustration, sub populations may incorporate adolescent couples, moderately aged couples, old couples, and previously wedded couples.
