Legal documents about an event are primary sources, while a book about the event is a secondary source. A company surveying customers about preferences and service issues is a source of primary data, while an article detailing and adding fresh insight to the survey results is a source of secondary data.
Combining Primary and Secondary Data Tertiary data is a compilation of primary and secondary data. This type of data includes sources like almanacs, textbooks and instruction manuals. The purpose of this type of compilation is to present a summary of repackaged primary and secondary data that is easier to process, notes the University of Minnesota Crookston. Facts About Primary and Secondary Data. Quick Answer A primary source is a first-hand assessment of a topic or event, while a secondary source is an interpretation of the primary data.
What Makes a Good Thesis Statement? Full Answer It is important to know the difference between primary and secondary data when studying, writing a paper or researching an issue. Learn more about Academic Essays. What Is the Purpose of Primary Research?
The motive of primary research is to gather data directly from the source as opposed to relying on secondary data that was already gathered. This column will help to explain the differences between primary and secondary data.
An advantage of using primary data is that researchers are collecting information for the specific purposes of their study. In essence, the questions the researchers ask are tailored to elicit the data that will help them with their study. Researchers collect the data themselves, using surveys, interviews and direct observations. In the field of workplace health research, for example, direct observations may involve a researcher watching people at work. The researcher could count and code the number of times she sees practices or behaviours relevant to her interest—e.
Part of the research may involve interviewing workers by telephone about how long they were off work and about their experiences with the return-to-work process. There are several types of secondary data. They can include information from the national population census and other government information collected by Statistics Canada. This term refers to data that is collected routinely as part of the day-to-day operations of an organization, institution or agency. There are any number of examples: The summary is kind of like a dummies guide to the research findings and conclusions.
Personally, I think that the summary is more than adequate. If I doubt the conclusions, I can also see if there is an expert somewhere who shares similar doubts and can present his views in an easily understood manner. Unless we are trained scientists ourselves, I think we will to some extent be at the mercy of professionals who ferret out the information and present their findings to us. Fortunately, there can be a wide spectrum of opinion about the research, so I think we can get a complete overview of the body of scientific opinion and draw our own conclusions.
Primary data can be hard to understand, especially for the lay public. For example, a lot of primary research is published in peer reviewed journals. These publications target a very specialized market and it would take a specialist to filter through the data collection models cited through the study, and judge the merits of the conclusions. I can go as far as understanding maybe the introduction and the gist of the conclusion, but all the meaty stuff in between that deals with mathematical formulas and such leaves me dazed.
ZsaZsa56 Post 3 nextcorrea - I tend to agree, the only problem is that primary data collection can be very expensive and take a very long time. Scientists and labs are reluctant to make this data available to anyone because they have invested so much money into gathering it.
They have a certain proprietary claim to it. In some cases this might slow down the goals of science but in other cases it might create a competitive spirit that advances innovation.
In a lot of cases this data can be reexamined and reworked to produce different secondary data. A lot of times this new secondary data can be as valuable as the original conclusions.
Its kind of like a novel. One person will read it and reach one conclusion. Another will read it and reach a drastically different conclusion. They are not necessarily competitive or mutually exclusive, they just draw on the same primary material. If there was this spirit of sharing in the sciences I think we would see a lot more breakthroughs. To hold it back suggests something fishy about their methodology or their statistical analysis. The number one principle of science is repeatability.
Secondary data is an analysis or interpretation of primary data as told to someone, with the primary data used as a basis to retell a version of the original story or present original data in a new way, as noted by Ithaca College Library.

A primary data source is an original data source, that is, one in which the data are collected firsthand by the researcher for a specific research purpose or project. Primary data can be collected in a number of ways. DATA COLLECTION PRIMARY & SECONDARY PRESENTATION BY: Amogh Kadam Rizwan Shaikh Prathmesh Parab.
