Data collection has become a necessity. Be it small or large companies, everyone is adopting various methods of data collection to get insights into data.
The insights are then used to prepare action plans. Let’s take a simple example:
A farmer wants to sow rice in his field. But before he does that, he needs to know the requirements of seeds, fertilizers, ways of irrigation, protection of crops & other things.
So, the farmer goes to neighboring farmers & government authorities to know about various techniques of paddy cultivation.

He uses data collection methods like Surveys, Observations, Interviews to gather insights into existing data which is then used to prepare a plan for paddy farming.
Similarly, many companies & businesses adopt various techniques of data collection to improve productivity & drive business growth. Let’s learn about 4 prominent ways to collect data.

Top 4 Methods of Data Collection


Questionnaires are one of the most used methods of data collection by businesses, large companies & government authorities.
In this method, a set of questions are asked or given to people. The questions are usually close-ended so that answers can be obtained
The data obtained can then be used to understand people’s perception of a particular product/service.
So companies will either improve the product or offer better services as per the inputs of the people/customers


Surveys are among the data collection techniques that are used by government, non-government authorities and companies. This process is similar to questionnaires.
Surveys are done by:
Government – For providing various schemes to people, Census & other purposes.
NGOs – To understand the conditions of the needy, literacy rate among children & other areas of need.
Companies – To get a better picture of employee productivity, operational efficiency percentage & more.


Interviews are more interactive as compared to questionnaires & surveys. A key to conducting an efficient interview is to know what kind of questions to ask.
So instead of asking a monotonous set of questions, you interact with the person & change the set of questions based on the response.
This might be a great way to collect data, but interviews are one of the most expensive methods of data collection as compared to others.


Observation is one of the types of data collection techniques that don’t involve asking questions.
Instead, the researcher/observer has to understand a particular scenario & derive data based on his/her judgement. This can prove to be beneficial if the derived data is unbiased.
However, if he/she is biased towards a particular person/product then the data obtained would be flawed which can affect the entire organization.
These are the top 4 methods of data collection that can be used by large & small enterprises to obtain insights into data & use it to enhance productivity & drive business growth.
