As opposed to secondary data which is easily accessible but are not pure as they have undergone through many statistical treatments. Thank you for the information it is of great importance to us as Anderson students who have the privilege to use internet for our assignments.

Key Differences Between Primary and Secondary Data The fundamental differences between primary and secondary data are discussed in the following points: The term primary data refers to the data originated by the researcher for the first time. Secondary data is the already existing data, collected by the investigator agencies and organisations earlier.
Primary data is a real-time data whereas secondary data is one which relates to the past. Primary data is collected for addressing the problem at hand while secondary data is collected for purposes other than the problem at hand. Primary data collection is a very involved process. On the other hand, secondary data collection process is rapid and easy. Primary data collection sources include surveys, observations, experiments, questionnaire, personal interview, etc.
On the contrary, secondary data collection sources are government publications, websites, books, journal articles, internal records etc. Primary data collection requires a large amount of resources like time, cost and manpower. Conversely, secondary data is relatively inexpensive and quickly available. If the data collected, are original and collected for the first time by a researcher or investigator then those are the primary data.
On the other hand, if the data are collected by using already available sources, then those are the secondary data. This is the main difference between Primary and Secondary data.
This article attempts to provide a better understanding of both types of data while elaborating the difference between the two types. Primary data are collected with the objective of identifying some specific factors needed by the researcher. For this purpose, he can use the questionnaires specifying the special factors that he needs to collect.
These data should not have been collected by another investigator previously in order to be primary data. Therefore, before collecting the primary data, it is crucial to investigate if there is any other source available with the information interested by the researcher. If someone is interested in obtaining the primary data, the most popular method is the questionnaires. The reason for this is, the researcher or the investigating entity can build up the questionnaires according to their requirements.
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. If you reach a result and you can't show to others how it was reached it can never be considered valid. There are so many statistics and surveys and studies that people reference these days, its important to separate the good information from the bad.

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.
Primary data is information that you collect specifically for the purpose of your research project. An advantage of primary data is that it is specifically tailored to your research needs. An advantage of primary data is that it is specifically tailored to .
Primary 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 . • Use of the secondary data is highly advisable if and only if they can be modeled according to your requirement, unless otherwise, there is a special purpose of conducting a primary data research despite the time and cost factors. • Gathering primary data can be very costly in comparison to secondary data gathering.

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.
