In a time once data is ending up being easily easily accessible to researchers almost everywhere the world, the practicality the utilizing second data for research study is becoming an ext prevalent, very same as that is questionable authenticity when contrasted with major data.

You are watching: A major disadvantage of primary data collection is

These 2 species of data, when considered for study is a double-edged sword due to the fact that it deserve to equally do a research project and it have the right to mar it.

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

It is because of this important for one to study the similarities and differences between these data varieties so regarding make ideal decisions when picking a far better data type for study work.

What is main Data?

Primary data is the sort of data that is built up directly indigenous the data resource without walking through any type of existing sources. The is mostly collected specially for a research project and also may be shared publicly to be used for various other research

Primary data is regularly reliable, authentic, and objective in as lot as that was gathered with the function of addressing a certain research problem. The is notable that primary data is no commonly built up because that the high price of implementation.


A usual example of major data is the data accumulated by organizations during market research, product research, and also competitive analysis. This data is collected directly from its original source which in most instances are the existing and potential customers.

Most that the human being who collect main data are government authorized agencies, investigators, research-based personal institutions, etc.

Primary data is particular to the demands of the researcher at the minute of data collection. The researcher is may be to regulate the type of data that is being collected.It is accurate compared to secondary data. The data is not subjected to an individual bias and as together the authenticity deserve to be trusted.Primary data is commonly up to date due to the fact that it collects data in real-time and also does no collect data indigenous old sources.


Primary data is an extremely expensive contrasted to second data. Therefore, it could be complicated to collect primary data.It is time-consuming.It may not it is in feasible to collect major data in some situations due come its complexity and also required commitment.

What is an additional Data?

Secondary data is the data that has actually been gathered in the previous by someone else but made obtainable for others to use. They room usually once primary data but become secondary when offered by a 3rd party.

Secondary data room usually easily easily accessible to researchers and individuals due to the fact that they are mainly shared publicly. This, however, way that the data space usually general and also not tailored specifically to satisfy the researcher"s demands as primary data does.


For example, when conducting a research study thesis, researchers need to consult past works done in this field and add findings to the literature review. Some other things favor definitions and theorems are secondary data the are included to the thesis come be appropriately referenced and also cited accordingly.

Some common sources of second data incorporate trade publications, government statistics, journals, etc. In many cases, these sources cannot it is in trusted as authentic.

Secondary data is easily accessible compared to primary data. An additional data is easily accessible on various platforms that can be accessed by the researcher.Secondary data is really affordable. That requires small to no expense to gain them due to the fact that they space sometimes given out for free.The time invested on collecting second data is normally very tiny compared to the of main data.Secondary data provides it feasible to carry out longitudinal researches without having actually to wait for a long time to draw conclusions.It help to generate new insights right into existing primary data.


Secondary data might not it is in authentic and also reliable. A researcher may need to more verify the data built up from the available sources.Researchers may have actually to attend to irrelevant data before finally detect the compelled data.Some of the data is exaggerated as result of the personal bias the the data source.Secondary data sources are occasionally outdated v no new data to change the old ones.

Here are 15 differences in between primary and an additional data


Primary data is the type of data the is accumulated by researchers directly from key sources while secondary data is the data the has already been collected through main sources and also made readily available for researchers to usage for their own research.

The main difference between these 2 interpretations is the truth that main data is collected from the main source of data, while secondary data is not.

The an additional data made easily accessible to researchers from existing sources are formerly primary data that was built up for research study in the past. The availability of an additional data is highly dependent on the primary researcher"s decision to share their data publicly or not.


An instance of major data is the nationwide census data gathered by the federal government while an example of secondary data is the data built up from digital sources. The an additional data gathered from an online source could be the primary data accumulated by an additional researcher.

For example, the government, after properly the nationwide census, re-superstructure the outcomes in newspapers, digital magazines, push releases, etc. An additional government company that is trying to allocate the state budget for healthcare, education, etc. Might need to access the census results.

With access to this information, the variety of children who needs education and learning can be analyzed and also hard to recognize the amount that should be allocated to the education sector. Similarly, learning the variety of old people will help in allocating funds because that them in the health and wellness sector.

Data Types

The type of data provided by major data is real-time, while the data provided by second data is stale. Researchers space able come have access to the most recent data when conducting major research, which might not it is in the situation for second data.

Secondary data need to depend on main data that has actually been accumulated in the past to execute research. In part cases, the researcher might be lucky that the data is built up close to the time that that or she is conducting research.

Therefore, reducing the lot of difference between the an additional data being used and the recent data.


Researchers room usually an extremely involved in the major data repertoire process, while secondary data is quick and also easy to collect. This is due to the truth that main research is greatly longitudinal.

Therefore, researchers have to spend a lengthy time performing research, record information, and analyzing the data. This data have the right to be accumulated and analyzed within a few hours once conducting an additional research.

For example, an organization may spend a lengthy time assessing the industry size for transport suppliers looking come talk right into the ride-hailing sector. A potential investor will certainly take this data and use the to inform his decision the investing in the ar or not.


Primary data is available in crude type while an additional data is available in a sleek form. The is, secondary data is typically made available to the general public in a simple type for a layman to recognize while main data space usually raw and will need to be simplified by the researcher.

Secondary data are this means because they have actually previously been damaged down by researchers who built up the major data afresh. A an excellent example is the Thomson Reuters yearly market reports that are made easily accessible to the public.

When Thomson Reuters collection this data afresh, they are usually raw and also may be complicated to understand. They simplify the results of this data through visualizing it v graphs, charts, and also explanations in words.

Data collection Tools

Primary data can be collected using surveys and also questionnaires while second data are built up using the library, bots, etc. The various ones between these data repertoire tools space glaring and can it be interchangeably used.

When collecting main data, researcher lookout because that a tool that deserve to be easily used and also can collect reputable data. One of the ideal primary data arsenal tools that accomplish this condition is bromheads.tvus.

bromheads.tvus is a web-based main data repertoire tool the helps researcher collect dependable data if simultaneously enhancing the response rate native respondents.


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

Primary data sources are sources that require a deep commitment indigenous researchers and require communication with the topic of study. Second data, top top the various other hand, do not require interaction with the topic of study prior to it can be collected.

In many cases, secondary researchers perform not have any interaction through the subject of research.


Primary data is always certain to the researcher"s needs, while secondary data may or may not be certain to the researcher"s needs. It depends solely on the sort of data the researcher had the ability to lay hand on.

Secondary researchers may be happy to have access to data tailored especially to meet their needs, i m sorry mag is no the instance in some cases. For example, a market researcher researching the purchasing power of civilization from a particular community might not have accessibility to the data of the subject community.

Alternatively, there might be one more community through a comparable standard of life to the subject neighborhood whose data is available. The researcher mag uses to clear up for this data and also use the to educate his conclusion top top the subject community.


Some common advantages of main data are its authenticity, certain nature, and also up to date information while second data is very cheap and not time-consuming.

Primary data is an extremely reliable due to the fact that it is normally objective and built up directly indigenous the original source. It also gives up-to-date information about a research study topic compared to an additional data.

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


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

For example, when physically interviewing study subjects, one might need one or an ext professionals, consisting of the interviewees, videographers that will make a record of the interview in part cases and also the people affiliated in preparing because that the interview. Personal from the moment required, the expense of act this may be fairly high.

Secondary data may be outdated and irrelevant. In fact, researchers need to surf with irrelevant data before finally having accessibility to the data pertinent to the research study purpose.

Accuracy and also Reliability

Primary data is an ext accurate and reliable while secondary data is relatively less reliable and accurate. This is mainly due to the fact that the second data sources are no regulated and are subject to personal bias.

A good example of this is business owners who lay bloggers come write great reviews about their product just to gain more customers. This is no the situation with major data i beg your pardon is built up by being a researcher himself.

One that the researcher"s intends when gathering major data for research study will it is in gathering accurate data so regarding arrive at correct conclusions. Therefore, biases will be avoided in ~ all prices (e.g. Very same businesses once collecting feedback indigenous customers).


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

In fact, a researcher might work with both major data and an additional data because that one research. This is usually an extremely advisable in cases by which the available an additional data go not completely meet the research needs.

Therefore, a small extension ~ above the available data will be done and cost will additionally be saved. For example, a researcher might require a market report indigenous 2010 to 2019 if the accessible reports protect against at 2018.

Collection Time

The time forced to collect primary data is usually long while that required to collect secondary data is usually short. The primary data collection procedure is periodically longitudinal in nature.

Therefore, researchers might need to watch the study subject for part time while taking down essential data. For example, when observing the actions of a group of civilization or specific species, researchers need to observe them for a while.

Secondary data can, however, be accumulated in a matter of minutes and also analyzed come dead conclusions—taking a shorter time when contrasted to main data. In part rare cases, specifically when collecting tiny data, second data might take a longer time because of an obstacle consulting different data resources to uncover the ideal data.

Similarities in between Primary & second Data

Contains exact same Content:

Secondary data to be once major data as soon as it was newly gathered by the first researcher. The content of the data gathered does not change and thus has the exact same content as main data.

It doesn"t matter if that was additional visualized in the second form, the contents does not change. A common example that these room definitions, theorems, and postulates that were made years back but still stay the same.


Primary data and second data room both used in research and also statistics. They can be offered to lug out the exact same kind of research in this fields relying on data availability. This is because an additional data and primary data have the same content. The only distinction is the technique by i m sorry they space collected.

Since the technique of repertoire does not directly impact the provides of data, they can be used to perform similar research. For example, whether accumulated directly or indigenous an existing database, the demography of a specific target market can be offered to inform similar business decisions.


When performing research, that is necessary to consider the obtainable data alternatives so regarding ensure the the right kind of data is provided to come at a feasibility conclusion. A great understanding that the various data types, similarities, and also differences are yet required to perform this.

Primary data and second data both have actually applications in business and research. Lock may, however, different from each various other in the means in i m sorry they are collected, used, and analyzed.
