In a time when data is ending up being easily easily accessible to researchers all over the world, the practicality of utilizing an additional data for research is becoming much more prevalent, exact same as the questionable authenticity when contrasted with major data.

You are watching: The main advantage of primary data is that they:

These 2 varieties of data, when considered for research is a double-edged sword since it have the right to equally do a research study project and it can mar it.

In a nutshell, major data and secondary data both have actually their advantages and disadvantages. Therefore, once carrying the end research, it is left because that the researcher to sweet these factors and also choose the much better one.

It is as such important because that one to research the similarities and differences in between these data varieties so regarding make ideal decisions when selecting a much better data type for research study work.

What is main Data?

Primary data is the kind of data the is gathered directly from the data source without walk through any kind of existing sources. That is mostly gathered specially for a research study project and may be common publicly to be supplied for various other research

Primary data is regularly reliable, authentic, and objective in as much as it was accumulated with the function of addressing a specific research problem. That is noteworthy that primary data is no commonly accumulated because the the high cost of implementation.


A typical example of primary data is the data collected by organizations throughout market research, product research, and also competitive analysis. This data is built up directly from its original resource which in most situations are the existing and also potential customers.

Most that the world who collect primary data are government authorized agencies, investigators, research-based exclusive institutions, etc.

Primary data is certain to the needs of the researcher at the minute of data collection. The researcher is able to control the type of data the is gift collected.It is accurate compared to an additional data. The data is not subjected to personal bias and as together the authenticity can be trusted.Primary data is usually up come date because it collects data in real-time and also does not collect data native old sources.


Primary data is really expensive contrasted to secondary data. Therefore, it might be an overwhelming to collect major data.It is time-consuming.It might not be feasible come collect primary data in some cases due come its complexity and also required commitment.

What is secondary Data?

Secondary data is the data that has been built up in the past by who else yet made obtainable for rather to use. They space usually once major data but become an additional when provided by a third party.

Secondary data space usually easily accessible to researchers and also individuals because they are mainly shared publicly. This, however, means that the data room usually general and also not tailored especially to fulfill the researcher"s demands as primary data does.


For example, as soon as conducting a study thesis, researchers must consult past works excellent in this ar and include findings to the literature review. Some various other things like definitions and also theorems are an additional data the are added to the thesis to be effectively referenced and cited accordingly.

Some typical sources of an additional data encompass trade publications, government statistics, journals, etc. In most cases, these sources cannot be trusted as authentic.

Secondary data is easily obtainable compared to major data. Secondary data is easily accessible on various platforms that have the right to be accessed by the researcher.Secondary data is very affordable. The requires little to no price to acquire them since they room sometimes offered out because that free.The time spent on collecting secondary data is generally very little compared to that of main data.Secondary data makes it feasible to carry out longitudinal research studies without having to wait because that a lengthy time to attract conclusions.It help to generate brand-new insights right into existing main data.


Secondary data may not it is in authentic and also reliable. A researcher might need to further verify the data collected from the available sources.Researchers may have actually to deal with irrelevant data before finally finding the forced data.Some of the data is exaggerated as result of the personal bias that the data source.Secondary data sources are occasionally outdated through no brand-new data to replace the old ones.

Here room 15 differences in between primary and second data


Primary data is the kind of data that is gathered by researchers straight from key sources while an additional data is the data the has already been gathered through primary sources and also made readily easily accessible for researchers to usage for their own research.

The key difference in between these 2 interpretations is the fact that main data is gathered from the main source of data, while second data is not.

The second data made easily accessible to researchers from existing resources are formerly primary data that was gathered for research study in the past. The ease of access of secondary data is highly dependent on the main researcher"s decision to share their data publicly or not.


An instance of primary data is the nationwide census data accumulated by the government while an example of secondary data is the data gathered from virtual sources. The secondary data gathered from one online resource could be the main data accumulated by another researcher.

For example, the government, after efficiently the national census, re-publishing the outcomes in newspapers, digital magazines, press releases, etc. One more government agency that is trying to allocate the state spending plan for healthcare, education, etc. May need to accessibility the census results.

With access to this information, the variety of children who needs education can be analyzed and hard to identify the amount that should be allocated come the education sector. Similarly, knowing the number of old world will assist in allocation funds for them in the health and wellness sector.

Data Types

The kind of data detailed by major data is real-time, when the data provided by an additional data is stale. Researchers room able to have access to the most recent data once conducting major research, which may not be the instance for second data.

Secondary data have to depend on primary data that has actually been built up in the previous to execute research. In part cases, the researcher might be lucky that the data is built up close to the moment that he or she is conducting research.

Therefore, reduce the lot of difference between the second data gift used and also the recent data.


Researchers are usually very involved in the main data arsenal process, while second data is quick and also easy to collect. This is because of the fact that primary research is mostly longitudinal.

Therefore, researchers have to spend a lengthy time performing research, record information, and assessing the data. This data can be collected and analyzed in ~ a couple of hours when conducting an additional research.

For example, an organization might spend a long time analyzing the sector size because that transport carriers looking to talk into the ride-hailing sector. A potential investor will certainly take this data and also use that to notify his decision of investing in the sector or not.


Primary data is easily accessible in crude form while an additional data is obtainable in a refined form. That is, secondary data is typically made accessible to the general public in a simple form for a layman to recognize while major data are usually raw and also will have to be streamlined by the researcher.

Secondary data are this method because they have actually previously been broken down by researchers who accumulated the major data afresh. A good example is the Thomson Reuters annual market reports that space made accessible to the public.

When Thomson Reuters collection this data afresh, they space usually raw and also may be complicated to understand. They leveling the outcomes of this data by visualizing it through graphs, charts, and explanations in words.

Data collection Tools

Primary data have the right to be accumulated using surveys and also questionnaires while second data are accumulated using the library, bots, etc. The different ones between these data collection tools space glaring and can it be interchangeably used.

When collecting main data, researcher lookout for a tool that can be conveniently used and can collect trusted data. Among the finest primary data repertoire tools that accomplish this condition is bsci-ch.orgus.

bsci-ch.orgus is a web-based primary data repertoire tool that helps researcher collect reputable data when simultaneously increasing the solution rate native respondents.


Primary data sources include; Surveys, observations, experiments, questionnaires, focus groups, interviews, etc., while an additional data resources include; books, journals, articles, internet pages, blogs, etc. These sources vary explicitly and also there is no intersection in between the primary and second data sources.

Primary data resources are resources that need a deep commitment native researchers and also require interaction with the topic of study. Secondary data, on the various other hand, execute not require interaction with the subject of study before it have the right to be collected.

In most cases, an additional researchers carry out not have any interaction through the topic of research.


Primary data is always specific to the researcher"s needs, while second data might or might not be particular to the researcher"s needs. It depends specifically on the type of data the researcher had the ability to lay hands on.

Secondary researchers may be lucky to have access to data tailored specifically to satisfy their needs, i m sorry mag is not the case in part cases. For example, a sector researcher researching the purchasing strength of civilization from a details community might not have accessibility to the data of the subject community.

Alternatively, there may be an additional community through a comparable standard of life to the subject community whose data is available. The researcher mag offers to settle for this data and use that to notify his conclusion on the subject community.


Some common benefits of major data room its authenticity, details nature, and also up to date information while second data is really cheap and also not time-consuming.

Primary data is really reliable since it is usually objective and collected directly from the original source. It also gives up-to-date information about a research study topic contrasted to secondary data.

Secondary day, top top the various other hand, is no expensive making it simple for civilization to conduct second research. It doesn"t take so lot time and also most that the second data sources have the right to be accessed because that free.


The disadvantage of primary data is the cost and time spent on data collection while an additional data might be outdated or irrelevant. Primary data incur so much cost and takes time since of the processes associated in transporting out major research.

For example, once physically interviewing study subjects, one might need one or an ext professionals, including the interviewees, videographers who will do a record of the interview in some cases and also the people involved in preparing because that the interview. Personally from the moment required, the cost of act this might be relatively high.

Secondary data may be outdated and irrelevant. In fact, researchers have to surf through irrelevant data before finally having access to the data relevant to the study purpose.

Accuracy and also Reliability

Primary data is an ext accurate and reliable while second data is fairly less reliable and accurate. This is mainly due to the fact that the secondary data sources are not regulated and also are topic to personal bias.

A an excellent example that this is organization owners that lay bloggers come write an excellent reviews around their product just to gain much more customers. This is no the situation with main data i m sorry is collected by being a researcher himself.

One of the researcher"s intends when gathering primary data for study will it is in gathering accurate data so regarding arrive at correct conclusions. Therefore, biases will certainly be avoided in ~ all prices (e.g. Exact same businesses as soon as collecting feedback indigenous customers).


Primary data is an extremely expensive while an additional data is economical. When working ~ above a low budget, that is better for researchers to work-related with an additional data, then analysis it come uncover brand-new trends.

In fact, a researcher might work with both major data and second data for one research. This is usually really advisable in cases by which the available second data walk not totally meet the study needs.

Therefore, a small extension on the accessible data will certainly be done and also cost will additionally be saved. Because that example, a researcher might require a sector report native 2010 come 2019 if the obtainable reports stop at 2018.

Collection Time

The time compelled to collect main data is usually long while that forced to collect second data is commonly short. The main data collection process is occasionally longitudinal in nature.

Therefore, researchers may need to watch the research study subject for some time while taking down crucial data. For example, once observing the actions of a group of civilization or specific species, researchers need to observe them because that a while.

Secondary data can, however, be gathered in a matter of minutes and also analyzed to dead conclusions—taking a shorter time when contrasted to major data. In some rare cases, especially when collecting tiny data, second data might take a much longer time since of an obstacle consulting different data sources to uncover the best data.

Similarities between Primary & secondary Data

Contains same Content:

Secondary data was once primary data when it was newly built up by the first researcher. The contents of the data built up does not change and because of this has the very same content as primary data.

It doesn"t issue if the was additional visualized in the an additional form, the contents does not change. A usual example of these space definitions, theorems, and also postulates the were make years ago but still stay the same.


Primary data and secondary data room both provided in research and statistics. They deserve to be provided to bring out the very same kind of research in these fields relying on data availability. This is because second data and also primary data have actually the exact same content. The only difference is the method by i beg your pardon they are collected.

Since the technique of repertoire does no directly influence the uses of data, they deserve to be supplied to perform similar research. For example, whether built up directly or from an existing database, the demography the a details target market deserve to be used to inform comparable business decisions.


When performing research, that is necessary to take into consideration the accessible data choices so as to ensure that the right kind of data is offered to come at a feasibility conclusion. A an excellent understanding that the different data types, similarities, and differences are yet required to perform this.

Primary data and second data both have actually applications in business and research. They may, however, different from each various other in the means in which they space collected, used, and analyzed.
