What is data collection?

The traditional definition of data collection might lead us to think of gathering information through surveys, observations, or interviews. However, the modern-age definition of data collection extends beyond conducting surveys and observations. It encompasses the systematic gathering and recording of any kind of information through digital or manual methods. Data collection can be as routine as a doctor logging a patient’s information into an electronic medical record system during each clinic visit, or as specific as keeping a record of mosquito nets delivered to a rural household.

Getting started with data collection

Before starting your data collection process, you must clearly understand what you aim to achieve and how you’ll get there. Below are some actionable steps to help you get started.

1. Define your goals

Defining your goals is a crucial first step. Engage relevant stakeholders and team members in an iterative and collaborative process to establish clear goals. It’s important that projects start with the identification of key questions and desired outcomes to ensure you focus your efforts on gathering the right information.

Start by understanding the purpose of your project– what problem are you trying to solve, or what change do you want to bring about? Think about your project’s potential outcomes and obstacles and try to anticipate what kind of data would be useful in these scenarios. Consider who will be using the data you collect and what data would be the most valuable to them. Think about the long-term effects of your project and how you will measure these over time. Lastly, leverage any historical data from previous projects to help you refine key questions that may have been overlooked previously.

Once questions and outcomes are established, your data collection goals may still vary based on the context of your work. To demonstrate, let’s use the example of an international organization working on a healthcare project in a remote area.

• If you’re a researcher , your goal will revolve around collecting primary data to answer specific questions. This could involve designing a survey or conducting interviews to collect first-hand data on patient improvement, disease or illness prevalence, and behavior changes (such as an increase in patients seeking healthcare).
• If you’re part of the monitoring and evaluation ( M&E) team , your goal will revolve around measuring the success of your healthcare project. This could involve collecting primary data through surveys or observations and developing a dashboard to display real-time metrics like the number of patients treated, percentage of reduction in incidences of disease,, and average patient wait times. Your focus would be using this data to implement any needed program changes and ensure your project meets its objectives.
• If you’re part of a field team , your goal will center around the efficient and accurate execution of project plans. You might be responsible for using data collection tools to capture pertinent information in different settings, such as in interviews takendirectly from the sample community or over the phone. The data you collect and manage will directly influence the operational efficiency of the project and assist in achieving the project’s overarching objectives.

2. Identify your data sources

The crucial next step in your research process is determining your data source. Essentially, there are two main data types to choose from: primary and secondary.

• Primary data is the information you collect directly from first-hand engagements. It’s gathered specifically for your research and tailored to your research question. Primary data collection methods can range from surveys and interviews to focus groups and observations. Because you design the data collection process, primary data can offer precise, context-specific information directly related to your research objectives. For example, suppose you are investigating the impact of a new education policy. In that case, primary data might be collected through surveys distributed to teachers or interviews with school administrators dealing directly with the policy’s implementation.
• Secondary data, on the other hand, is derived from resources that already exist. This can include information gathered for other research projects, administrative records, historical documents, statistical databases, and more. While not originally collected for your specific study, secondary data can offer valuable insights and background information that complement your primary data. For instance, continuing with the education policy example, secondary data might involve academic articles about similar policies, government reports on education or previous survey data about teachers’ opinions on educational reforms.

While both types of data have their strengths, this guide will predominantly focus on primary data and the methods to collect it. Primary data is often emphasized in research because it provides fresh, first-hand insights that directly address your research questions. Primary data also allows for more control over the data collection process, ensuring data is relevant, accurate, and up-to-date.

However, secondary data can offer critical context, allow for longitudinal analysis, save time and resources, and provide a comparative framework for interpreting your primary data. It can be a crucial backdrop against which your primary data can be understood and analyzed. While we focus on primary data collection methods in this guide, we encourage you not to overlook the value of incorporating secondary data into your research design where appropriate.

3. Choose your data collection method

When choosing your data collection method, there are many options at your disposal. Data collection is not limited to methods like surveys and interviews. In fact, many of the processes in our daily lives serve the goal of collecting data, from intake forms to automated endpoints, such as payment terminals and mass transit card readers. Let us dive into some common types of data collection methods:

Surveys and Questionnaires

Surveys and questionnaires are tools for gathering information about a group of individuals, typically by asking them predefined questions. They can be used to collect quantitative and qualitative data and be administered in various ways, including online, over the phone, in person (offline), or by mail.

• Advantages : They allow researchers to reach many participants quickly and cost-effectively, making them ideal for large-scale studies. The structured format of questions makes analysis easier.
• Disadvantages : They may not capture complex or nuanced information as participants are limited to predefined response choices. Also, there can be issues with response bias, where participants might provide socially desirable answers rather than honest ones.

Interviews

Interviews involve a one-on-one conversation between the researcher and the participant. The interviewer asks open-ended questions to gain detailed information about the participant’s thoughts, feelings, experiences, and behaviors.

• Advantages : They allow for an in-depth understanding of the topic at hand. The researcher can adapt the questioning in real time based on the participant’s responses, allowing for more flexibility.
• Disadvantages : They can be time-consuming and resource-intensive, as they require trained interviewers and a significant amount of time for both conducting and analyzing responses. They may also introduce interviewer bias if not conducted carefully, due to how an interviewer presents questions and perceives the respondent, and how the respondent perceives the interviewer.

Observations

Observations involve directly observing and recording behavior or other phenomena as they occur in their natural settings.

• Advantages : Observations can provide valuable contextual information, as researchers can study behavior in the environment where it naturally occurs, reducing the risk of artificiality associated with laboratory settings or self-reported measures.
• Disadvantages : Observational studies may suffer from observer bias, where the observer’s expectations or biases could influence their interpretation of the data. Also, some behaviors might be altered if subjects are aware they are being observed.

Focus Groups

Focus groups are guided discussions among selected individuals to gain information about their views and experiences.

• Advantages : Focus groups allow for interaction among participants, which can generate a diverse range of opinions and ideas. They are good for exploring new topics where there is little pre-existing knowledge.
• Disadvantages : Dominant voices in the group can sway the discussion, potentially silencing less assertive participants. They also require skilled facilitators to moderate the discussion effectively.

Forms

Forms are standardized documents with blank fields for collecting data in a systematic manner. They are often used in fields like Customer Relationship Management (CRM) or Electronic Medical Records (EMR) data entry. Surveys may also be referred to as forms.

• Advantages : Forms are versatile, easy to use, and efficient for data collection. They can streamline workflows by standardizing the data entry process.
• Disadvantages : They may not provide in-depth insights as the responses are typically structured and limited. There is also potential for errors in data entry, especially when done manually.

Selecting the right data collection method should be an intentional process, taking into consideration the unique requirements of your project. The method selected should align with your goals, available resources, and the nature of the data you need to collect.

If you aim to collect quantitative data, surveys, questionnaires, and forms can be excellent tools, particularly for large-scale studies. These methods are suited to providing structured responses that can be analyzed statistically, delivering solid numerical data.

However, if you’re looking to uncover a deeper understanding of a subject, qualitative data might be more suitable. In such cases, interviews, observations, and focus groups can provide richer, more nuanced insights. These methods allow you to explore experiences, opinions, and behaviors deeply. Some surveys can also include open-ended questions that provide qualitative data.

The cost of data collection is also an important consideration. If you have budget constraints, in-depth, in-person conversations with every member of your target population may not be practical. In such cases, distributing questionnaires or forms can be a cost-saving approach.

Additional considerations include language barriers and connectivity issues. If your respondents speak different languages, consider translation services or multilingual data collection tools . If your target population resides in areas with limited connectivity and your method will be to collect data using mobile devices, ensure your tool provides offline data collection , which will allow you to carry out your data collection plan without internet connectivity.
