Secondary analysis affords researchers the opportunity to investigate research questions using large-scale data sets that are often inclusive of under-represented groups, while saving time and resources.

Secondary Data

Data collected originally by the researcher himself for the purpose of his study are known as primary data datum is the singular form of data. The researcher gets firsthand information from the respondents. The researcher contacts the respondents personally and obtains all the relevant information for his study. This approach is used when it is not possible to get the information directly from the parties concerned. For example, if the study is on addiction to alcohol, the required information can be better secured by approaching those who are closely related to the addict.

Primary sources of data collection have their advantages such as addressing specific research problems and applications in data management and storage. On the other hand, secondary data gathering has also a range of benefits, best practices, and important meaning in the marketing and data world. For each type of business to be successful, it is absolutely crucial to have reliable information for the market and customer characteristics. This is where intensive research methods and data collection tools come to make it possible. Primary data is information collected directly from first-hand experience.

Одно только ее беспокоило: всякий раз, когда они куда-то ходили, он решительно противился тому, чтобы она сама платила за. Сьюзан не могла с этим смириться, видя, как он выкладывает за их обед свою дневную заработную плату, но спорить с ним было бесполезно. Она в конце концов перестала протестовать, но это продолжало ее беспокоить. Я зарабатываю гораздо больше, чем в состоянии потратить, - думала она, - поэтому будет вполне естественным, если я буду платить.
