Primary data is data which has been collected by yourself, which is more reliable and up to date. Secondary data has been collected from a secondary source (Other people, business etc.) so it may not be valid or up to date."Primary" and "secondary" are terms used to define data relative to the purpose by which the data were collected originally."Primary data" are data collected for the need at hand."Secondary data" are data that were collected for another reason but is being re-purposed to address the need at hand.When describing the expertise of data analysts, it is not uncommon to distinguish between primary and secondary data analytics. Primary data analytics involves the ability to analyze data for the purpose by which it has been collected. Secondary data analytics involves identifying "secondary data sources" to solve a new problem and then the ability to re-purpose that data.Primary data is a data which is created for the first time and there is no previous source available. Secondary data is a readily available data like data from trade directories,statistics from websites etc. In Dissertation Literature review is done through secondary data which includes the contents such as theories, models, compilation, research findings by some other scholar etc.
π Primary Data Definition: Data collected directly from the source for a specific research purpose. Examples: Surveys or questionnaires Interviews (face-to-face, phone, online) Observations or experiments Focus groups Field research Key Features: Collected firsthand Original and specific to your goals Usually more accurate and current Time-consuming and costly to gather π Secondary Data Definition: Data that has already been collected by someone else for a different purpose, but is reused for your research. Examples: Government reports (e.g., census data) Academic journals or research papers Business databases and market research reports News articles or publications Company annual reports or case studies Key Features: Pre-existing data Faster and cheaper to access May not be tailored to your specific needs Might be outdated or biased
Supplementary Services are services that are considered secondary to the primary service a business holds. A cinema, for example, offers refreshments as a secondary service to their purpose of individuals viewing films.
how is data collected and used for the purpose of national statistics
I've never heard of primary vs. secondary sources ofreading, but I can provide an answer on primary vs. secondary sources of data.A secondary source of data is data that was collected for a reason other than the task at hand. A good example is US Census data. Marketers might use census data as input into decisions. An example of application of this data is as follows. Suppose you want to distribute your product in the 5 most populated cities in the US. You could find this info from census data, and go about distributing your product in those 5 cities.A primary source of data is data that is collected specifically for the task at hand, often via a market research study. For example, if you wanted to know what features of your product are most valued to buyers, you would design a market research study (i.e. questionnaire) to find that out. At the end of your study, you'd have the data to answer your question.---Note that there is quite a trade in used data. There's nothing wrong in this, provided all the relevant information about things like the purpose and reliability and possible sources of distortion of the old data are taken into account.
Secondary use is using data for a purpose other than the purpose it was collected for.

Data can be classified according to source into primary and secondary data. Primary data is collected firsthand by the researcher for a specific purpose, such as surveys or experiments. In contrast, secondary data is obtained from existing sources, such as books, articles, or databases, which were originally collected by someone else for a different purpose. Understanding the source of data helps assess its reliability and relevance for research or analysis.
Primary data is data collected firsthand by an individual or organization for a specific purpose through methods like surveys, interviews, or experiments. Secondary data, on the other hand, is data that has been previously collected for another purpose by someone else and is being used by another party for their research or analysis.
When the primary and secondary voltages are the same the transformer is being used for isolation. The secondary side will have galvanic isolation from the primary side. The purpose of the is to protect secondary load if a fault occurs on the primary side. The impedance of the transformer will limit the fault current on the secondary which should save equipment.

An article can be considered either a primary or secondary source, depending on its content and purpose. If the article presents original research findings or firsthand accounts of events, it is a primary source. If the article analyzes or interprets existing research or data, it is a secondary source.
The primary purpose of Advent is to prepare for the celebration of the birth of Our Lord on Christmas Day. The secondary purpose is to prepare for His Second Coming at the end of time.
