What is Data Collection?

Data collection is a methodical process of gathering and analyzing specific information to proffer solutions to relevant questions and evaluate the results. It focuses on finding out all there is to a particular subject matter.

Data is collected to be further subjected to hypothesis testing which seeks to explain a phenomenon. Hypothesis testing eliminates assumptions while making a proposition from the basis of reason.

For collectors of data, there is a range of outcomes for which the data is collected. But the key purpose for which data is collected is to put a researcher in a vantage position to make predictions about future probabilities and trends.

The core forms in which data can be collected are primary and secondary data. While the former is collected by a researcher through first-hand sources, the latter is collected by an individual other than the user. 

Types of Data Collection 

Before broaching the subject of the various types of data collection. It is pertinent to note that data collection in itself falls under two broad categories; Primary data collection and secondary data collection.

Primary Data Collection

Primary data collection by definition is the gathering of raw data collected at the source. It is a process of collecting the original data collected by a researcher for a specific research purpose. It could be further analyzed into two segments; qualitative research and quantitative data collection methods. 

  • Qualitative Research Method 

The qualitative research methods of data collection does not involve the collection of data that involves numbers or a need to be deduced through a mathematical calculation, rather it is based on the non-quantifiable elements like the feeling or emotion of the researcher. An example of such a method is an open-ended questionnaire.


  • Quantitative Method

Quantitative methods are presented in numbers and require a mathematical calculation to deduce. An example would be the use of a questionnaire with close-ended questions to arrive at figures to be calculated Mathematically. Also, methods of correlation and regression, mean, mode and median.

Secondary Data Collection

Secondary data collection, on the other hand, is referred to as the gathering of second-hand data collected by an individual who is not the original user. It is the process of collecting data that is already existing, be it already published books, journals and/or online portals. In terms of ease, it is much less expensive and easier to collect.

Your choice between Primary data collection and secondary data collection depend on the nature, scope and area of your research as well as its aims and objectives. 


There are a bunch of underlying reasons for collecting data, especially for a researcher. Walking you through them, here are a few reasons; 

  • Integrity of The Research

A key reason for collecting data, be it through quantitative or qualitative methods is to ensure that the integrity of the research question is indeed maintained.

  • Reduce the likelihood of errors

The correct use of appropriate data collection of methods reduces the likelihood of errors consistent with the results. 

  • Decision Making

To minimize the risk of errors in decision making, it is important that accurate data is collected so that the researcher doesn't make uninformed decisions. 

  • Save Cost and Time

Data collection saves the researcher time and funds that would otherwise be misspent without a deeper understanding of the topic or subject matter.

  • To support a need for a new idea, change and/or innovation

To prove the need for a change in the norm or the introduction of new information that will be widely accepted, it is important to collect data as evidence to support these claims.

An interview is a face-to-face conversation between two individuals with the sole purpose of collecting relevant information to satisfy a research purpose. Interviews are of different types namely; Structured, Semi-structured and unstructured with each having a slight variation from the other.

  • Structured Interviews - Simply put, it is a verbally administered questionnaire. In terms of depth, it is surface level and is usually completed within a short period. For speed and efficiency, it is highly recommendable, but it lacks depth. 
  • Semi-structured Interviews - In this method, there subsist several key questions which cover the scope of the areas to be explored. It allows a little more leeway for the researcher to explore the subject matter.
  • Unstructured Interviews - It is an in-depth interview that allows the researcher to collect a wide range of information with a purpose. An advantage of this method is the freedom it gives a researcher to combine structure with flexibility even though it is more time-consuming. 


  • In-depth information
  • Freedom of flexibility
  • Accurate data.


  • Time-consuming
  • Expensive to collect.


This is the process of collecting data through an instrument consisting of a series of questions and prompts to receive a response from individuals it is administered to. Questionnaires are designed to collect data from a group. 

For clarity, it is important to note that a questionnaire isn't a survey, rather it forms a part of it. A survey is a process of data gathering involving a variety of data collection methods, including a questionnaire.

On a questionnaire, there are three kinds of questions used. They are; fixed-alternative, scale, and open-ended. With each of the questions tailored to the nature and scope of the research.

  • Easy to visualize and analyze.
  • Questionnaires offer actionable data.

  • Questionnaires can cover all areas of a topic.
  • Relatively inexpensive.


  • Answers may be dishonest or the respondents lose interest midway.
  • Questionnaires can't produce qualitative data.
  • Questions might be left unanswered. 
  • Respondents may have a hidden agenda.

The opposite of quantitative research which involves numerical based data, this data collection method focuses more on qualitative research. It falls under the primary category for data based on the feelings and opinions of the respondents. This research involves asking open-ended questions to a group of individuals usually ranging from 6-10 people, to provide feedback.


  • Information obtained is usually very detailed.
  • Cost-effective when compared to one-on-one interviews.
  • It reflects speed and efficiency in the supply of results.


  • Lacking depth in covering the nitty-gritty of a subject matter.
  • Bias might still be evident.
  • Requires interviewer training
  • The researcher has very little control over the outcome.
  • A few vocal voices can drown out the rest.
  • Difficulty in assembling an all-inclusive group.

Also under the primary category, it is a combination of Interviews and Focus Groups while collecting qualitative data. This method is key when addressing sensitive subjects. 


  • Encourage participants to give responses.
  • It stimulates a deeper connection between participants.
  • The relative anonymity of respondents increases participation.
  • It improves the richness of the data collected.


  • It costs the most out of all the top 7.
