Transcripts

Data collection methods are ways of directly measuring variables and gathering information.

They allow you to gain first-hand knowledge and original insights into your research problem.

You can choose just one data collection method, or use several methods in the same study.

Let’s dive into a few of the most common choices, and look at some concrete examples

of how you can use different methods.

Surveys allow you to collect data about opinions, behaviours, experiences, and demographic characteristics

by asking people directly.

There are two main survey methods to choose from:

Ask people to fill out questionnaires themselves.

Conduct interviews where you ask questions and record the answers.

Questionnaires are more common in quantitative research.

They usually include closed questions with multiple-choice answers or rating scales.

This allows you to collect consistent data from many people and analyze the responses

statistically.

For example, if you want to measure students’ satisfaction with their online classes, you

could use a questionnaire to collect responses from many students.

Interviews are more common in qualitative research.

They usually allow participants to answer questions in their own words.

For example, you could conduct interviews to understand how teachers prepare for online

classes and explore which aspects they struggle with.

Unlike with questionnaires, you can ask follow-up questions and explore ideas in more depth.

However, interviewing is more time-consuming and usually involves a smaller group of participants.

Observations allow you to collect data unobtrusively, observing characteristics, behaviours or social

interactions without relying on self-reporting.

For example, to research teachers’ skills in online teaching, you could observe their

classes directly.

Observations may be conducted in real time, taking notes as you observe, or you might

make audiovisual recordings for later analysis.

Quantitative observation involves systematically measuring or counting specific events, behaviours,

characteristics, etc.

With this method, it’s important to have clear, objective rules to ensure you count

the same thing consistently.

For example, let’s say you’re collecting data on how often teachers have tech problems

– does an internet connection issue count, or will you only include problems that are

within the teacher’s control?

You need to clearly define the categories and criteria of your observation in advance.

Qualitative observation involves taking detailed notes and writing rich descriptions of what

is observed.

This means you don’t have to decide in advance how to categorize your observations.

For example, in an ethnographic study, you might take notes describing how students and

teachers interact in the online environment.

In theory, observations allow you to collect data on how people really behave (and not

just how they say they do).

But keep in mind that being observed may make people behave differently than they normally

would.

There are many other data collection methods that are common in different fields.

Here are a few examples:

In media and communication, you might collect a sample of texts to be analyzed (e.g. speeches,

articles, or social media posts).

In psychology, you might use technologies like neuroimaging, eye-tracking, or computer-based

tasks to measure things like attention or reaction time.

In education, you might use tests or assignments to collect data about knowledge and skills.

In the physical sciences, you might use scientific instruments to measure things like weight,

blood pressure, or chemical composition.

But wait – what if you don’t have the time or resources to collect data from the

population you want to study?

Instead of collecting your own data, you can use secondary data that other researchers

already collected – for example, datasets from government surveys or previous studies

on your topic.

With this raw data, you can do your own analysis to answer new research questions that weren’t

addressed by the original study.

Using secondary data gives you access to much larger and more varied samples than you could

collect yourself.

However, it also means you don’t have any control over which variables to measure or

how to measure them, so the conclusions you can draw may be limited.

If you’re struggling to choose the best methods for your research, try reading relevant

studies in your field to see how they went about it.

Once you know which methods you want to use, you also need to plan the details of how you’ll

use them.
