Question

What are the advantages and disadvantages of a research based upon secondary data alone? Can all researches be primary data based? Why or why not?

Answer 1

Secondary data is the information that has been as of now gathered from different sources and is also accessible from different sources. Such information is less expensive and more rapidly possible than the essential information and furthermore might be accessible when essential information cannot be gotten by any stretch of the imagination. The analysis of Secondary data is the utilization of information that was gathered by another person for some other reason.

Advantages

• The greatest preferred position of utilizing secondary information is that it very well may be progressively prudent. Another person has just gathered the information, so the analyst doesn't need to commit cash, time, vitality and assets to this period of research. In some cases the secondary informational index must be bought, however, the expense is quite often lower than the cost of gathering a comparable informational collection without any preparation, which for the most part involves compensations, travel and transportation, office space, gear, and other overhead expenses. What's more, since the information is as of now gathered and typically cleaned and put away in an electronic arrangement, the analyst can invest the majority of their energy breaking down the information as opposed to preparing the information for examination.
• A subsequent significant preferred advantage of utilizing secondary information is the expansiveness of information accessible. The government directs various examinations on an enormous, national scale that singular specialists would make some troublesome memories gathering. A significant number of these information collections are likewise longitudinal, implying that similar information has been gathered from a similar populace more than a few diverse timespans. This permits specialists to take a view of patterns and changes of marvels after some time.
• The information assortment process regularly keeps up a degree of ability and polished methodology that may not be available with singular specialists or little research ventures. For instance, information assortment for some, government informational indexes are regularly performed by staff individuals who represent considerable authority in specific undertakings and have numerous long stretches of involvement with that specific zone and with that specific overview. Numerous small research ventures don't have that degree of aptitude, the information is gathered by people working low maintenance.

Disadvantages

• A significant hindrance to utilizing secondary information is that it may not answer the analyst's particular research questions or contain explicit data that the specialist might want to have. It additionally might not have been gathered in the geographic locale or during the years wanted, or with the particular populace that the analyst is keen on considering. For instance, a scientist who is keen on considering youths may find that the optional informational collection just incorporates youthful grown-ups.
• Moreover, since the specialist didn't gather the information, they have no influence over what is contained in the informational collection. In many cases, this can restrain the examination or adjust the first inquiries the scientist looked to reply to. For instance, an analyst who is examining satisfaction and good faith may locate that an optional informational index just incorporates one of these factors, however not both.
• A related issue is that the factors may have been characterized or sorted uniquely in contrast to the scientist would have picked. For instance, age may have been gathered in classifications as opposed to as a constant variable, or race might be characterized as "white" and "other" rather than containing classes for each significant race.
• Another critical detriment of utilizing secondary information is that the analyst doesn't know precisely how the information assortment process was done or how well it was completed. The analyst isn't typically conscious of data about how true the information is influenced by issues, for example, low reaction rate or respondent misconception of explicit review questions. Now and again this data is promptly accessible, similar to the case with numerous government informational collections. In any case, numerous other auxiliary informational collections are not joined by this kind of data and the expert must figure out how to figure out the real story so as to reveal any potential impediments of the information.

Information is one of the most significant and essential parts of any examination. No, all researches cannot be primary data based as every study is unique and it depends upon the researchers that how they want to carry out their study. Analysts directed in various fields of study can be diverse in approach yet every exploration depends on information that is investigated and deciphered to get data. Although primary data is more accurate and unique but in some cases but secondary information will, in general, be promptly accessible and cheap to acquire.
