Distinguish between primary data and secondary data .
Answers
Answer:
Primary data is the type of data that is collected by researchers directly from main sources while secondary data is the data that has already been collected through primary sources and made readily available for researchers to use for their own research.
The main difference between these 2 definitions is the fact that primary data is collected from the main source of data, while secondary data is not.
The secondary data made available to researchers from existing sources are formerly primary data which was collected for research in the past. The availability of secondary data is highly dependent on the primary researcher's decision to share their data publicly or not.
Examples:
An example of primary data is the national census data collected by the government while an example of secondary data is the data collected from online sources. The secondary data collected from an online source could be the primary data collected by another researcher.
For example, the government, after successfully the national census, they share the results in newspapers, online magazines, press releases, etc. Another government agency that is trying to allocate the state budget for healthcare, education, etc. may need to access the census results.
With access to this information, the number of children who needs education can be analyzed and hard to determine the amount that should be allocated to the education sector. Similarly, knowing the number of old people will help in allocating funds for them in the health sector.
Data Types
The type of data provided by primary data is real-time, while the data provided by secondary data is stale. Researchers are able to have access to the most recent data when conducting primary research, which may not be the case for secondary data.
Secondary data have to depend on primary data that has been collected in the past to perform research. In some cases, the researcher may be lucky that the data is collected close to the time that he or she is conducting research.
Therefore, reducing the amount of difference between the secondary data being used and the recent data.
Process
Researchers are usually very involved in the primary data collection process, while secondary data is quick and easy to collect. This is due to the fact that primary research is mostly longitudinal.
Therefore, researchers have to spend a long time performing research, recording information, and analyzing the data. This data can be collected and analyzed within a few hours when conducting secondary research.
For example, an organization may spend a long time analyzing the market size for transport companies looking to talk into the ride-hailing sector. A potential investor will take this data and use it to inform his decision of investing in the sector or not.
