In a time when data is becoming easily accessible to researchers all over the world, the practicality of utilizing secondary data for research is becoming more prevalent, same as its questionable authenticity when compared with primary data. These 2 types of data, when considered for research is a double-edged sword because it can equally make a research project as well as it can mar it.

Secondary Research- Definition, Methods and Examples.
Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing. Data is collected and analyzed; data only becomes information suitable for making decision in some fashion.
Gathering data can be accomplished through a primary source researcher is the first person to obtain the data or a secondary source the researcher obtains the data that has already been collected by other sources, such as data disseminated in a scientific journal Mesly, Distinguish between primary data and secondary data Data collection plays a very crucial role in the statistical analysis. In research, there are different methods used to gather information, all of which fall into two categories, i.
As the name suggests, primary data is one which is collected for the first time by the researcher while secondary data is the data already collected or produced by others. There are many differences between primary and secondary data, which are discussed in this work. But the most important difference is that primary data is factual and original whereas secondary data is just the analysis and interpretation of the primary data. While primary data is collected with an aim for getting solution to the problem at hand, secondary data is collected for other purposes.
The fundamental differences between primary and secondary data are; the term primary data refers to the data originated by the researcher for the first time while secondary data is the already existing data collected by the investigator agencies and organisations earlier. 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 sources include surveys, observations, experiments, questionnaire, personal interview etc. Surveys are used in different areas for collecting the data even in public and private sectors. A survey may be conducted in the field by the researcher. The respondents are contacted by the research person personally, telephonically or through mail.
This method takes a lot of time, efforts and money but the data collected are of high accuracy, current and relevant to the topic. When the questions are administered by a researcher, the survey is called a structured interview or a researcher- administered survey. Observations: Observation as one of the primary sources of data. Observation is a technique for obtaining information involves measuring variables or gathering of data necessary for measuring the variable under investigation.
Observation is defined as accurate watching and noting of phenomena as they occur in nature with regards to cause and effect relation. Interviews can be undertaken on a personal one-to-one basis or in a group.
Questionnaires: Questionnaire as one of the primary sources of data is an observational technique which comprises series of items presented to a respondent in a written form, in which the individual is expected to respond in writing.
Here the respondents are given list of written items which he responds to by ticking the one he considers appropriate. While secondary sources means data collected by someone else earlier. Secondary data are the data collected by a party not related to the research study but collected these data for some other purpose and at different time in the past.
If the researcher uses these data then these become secondary data for the current users. Sources of secondary data are government publications websites, books, journal articles, internal records. As opposed to secondary data which is easily accessible but are not pure as they have undergone through many statistical treatments. Creating models in psychological research.

Primary sources of data collection have their advantages such as addressing specific research problems and applications in data management and storage. On the other hand, secondary data gathering has also a range of benefits, best practices, and important meaning in the marketing and data world. For each type of business to be successful, it is absolutely crucial to have reliable information for the market and customer characteristics. This is where intensive research methods and data collection tools come to make it possible. Primary data is information collected directly from first-hand experience.
In a time when data is becoming easily accessible to researchers all over the world, the practicality of utilizing secondary data for research is becoming more prevalent, same as its questionable authenticity when compared with primary data. These 2 types of data, when considered for research is a double-edged sword because it can equally make a research project as well as it can mar it. In a nutshell, primary data and secondary data both have their advantages and disadvantages.
Qualitative data collection methods
Secondary data refers to data that is collected by someone other than the primary user. Secondary data analysis can save time that would otherwise be spent collecting data and, particularly in the case of quantitative data , can provide larger and higher-quality databases that would be unfeasible for any individual researcher to collect on their own. However, secondary data analysis can be less useful in marketing research, as data may be outdated or inaccurate. Government departments and agencies routinely collect information when registering people or carrying out transactions, or for record keeping — usually when delivering a service. This information is called administrative data. A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population.
- Я думал, что… - Ладно, не в этом. В главном банке данных происходит нечто странное. Джабба взглянул на часы. - Странное? - Он начал беспокоиться. - Можешь выражаться яснее. Две минуты спустя Джабба мчался вниз к главному банку данных. ГЛАВА 85 Грег Хейл, распластавшись, лежал на полу помещения Третьего узла.
Коммандер. Нет. Сьюзан словно окаменела, ничего не понимая. Эхо выстрела слилось с царившим вокруг хаосом. Сознание гнало ее вперед, но ноги не слушались. Коммандер. Мгновение спустя она, спотыкаясь, карабкалась вверх по ступенькам, совершенно забыв о таящейся внизу опасности.
Поскольку в шифровалке имелось автономное энергоснабжение, на главный распределительный щит, наверное, даже не поступил сигнал, что здесь произошла авария. - Основное энергоснабжение вырубилось, - сказал Стратмор, возникший за спиной Сьюзан.
- Он направился к полке с ячейками для ключей и почты. - Быть может, я мог бы позвонить в номер и… - Простите, - сказал консьерж, и вся его любезность мгновенно улетучилась. - В Альфонсо Тринадцатом строгие правила охраны приватности постояльцев.
Таблица умножения, - сказал Беккер. При чем здесь таблица умножения? - подумала Сьюзан. - Что он хочет этим сказать. - Четыре на шестнадцать, - повторил профессор.
Один из прямоугольников вдруг закрыла чья-то тень. Даже не взглянув на верхушку башни, Халохот бросился к лестнице.
В трех тысячах миль от Вашингтона мини-автобус мобильного наблюдения мчался по пустым улицам Севильи. Он был позаимствован АНБ на военной базе Рота в обстановке чрезвычайной секретности. Двое сидевших в нем людей были напряжены до предела: они не в первый раз получали чрезвычайный приказ из Форт-Мида, но обычно эти приказы не приходили с самого верха. Агент, сидевший за рулем, повернув голову, бросил через плечо: - Есть какие-нибудь следы нашего человека. Глаза его партнера не отрывались от картинки на большом мониторе, установленном под крышей мини-автобуса.
Туда и обратно, - мысленно повторял. - Туда и обратно. Он был настолько погружен в свои мысли, что не заметил человека в очках в тонкой металлической оправе, который следил за ним с другой стороны улицы.
- Она не дала ему договорить.
