Q & A
What are data collection methods?
-Data collection methods are various ways to directly measure variables and gather information, allowing researchers to gain first-hand knowledge and original insights into their research problems.
Can a researcher use multiple data collection methods in the same study?
-Yes, a researcher can choose to use just one data collection method or combine several methods in the same study to obtain a comprehensive understanding of the research problem.
What are the two main survey methods mentioned in the script?
-The two main survey methods are self-administered questionnaires and interviews conducted by the researcher where questions are asked and answers are recorded.
Why are questionnaires more common in quantitative research?
-Questionnaires are more common in quantitative research because they usually include closed questions with multiple-choice answers or rating scales, allowing for the collection of consistent data from many people for statistical analysis.
How do interviews differ from questionnaires in terms of data collection?
-Interviews are more common in qualitative research, allowing participants to answer questions in their own words, providing the opportunity for follow-up questions and deeper exploration of ideas, unlike questionnaires.
What is an example of using a questionnaire for research?
-An example of using a questionnaire is to measure students' satisfaction with their online classes by collecting responses from a large number of students.
What are the benefits of using observations in data collection?
-Observations allow for the unobtrusive collection of data on characteristics, behaviors, or social interactions without relying on self-reporting, providing insights into how people actually behave.
How does quantitative observation differ from qualitative observation?
-Quantitative observation involves systematically measuring or counting specific events or behaviors with clear, objective rules, while qualitative observation involves taking detailed notes and writing rich descriptions without pre-defined categories.
What are some potential issues with relying solely on observations?
-One potential issue with observations is the 'Hawthorne effect,' where the act of being observed may cause people to behave differently than they normally would.
Can you provide an example of using secondary data in research?
-An example of using secondary data is accessing datasets from government surveys or previous studies to perform new analyses and answer different research questions.
What are the limitations of using secondary data in research?
-Using secondary data limits the researcher's control over which variables are measured and how they are measured, which may restrict the conclusions that can be drawn from the analysis.
How can a researcher choose the best methods for their study?
-A researcher can choose the best methods for their study by reading relevant studies in their field to understand how others have approached similar research problems.

Observations enable unobtrusive data collection by directly observing behaviors or social interactions.
Quantitative observation requires clear, objective rules for consistent measurement of specific events or behaviors.
Qualitative observation involves detailed notes and rich descriptions without pre-defined categorization.
Observations provide data on actual behaviors, but being observed may influence participants' actions.
Secondary data usage allows researchers to analyze pre-collected datasets to answer new research questions.
Using secondary data provides access to larger and more varied samples but limits control over variables.
Researchers can utilize various data collection methods depending on their field, such as media analysis or neuroimaging in psychology.
In education, tests and assignments can be used to collect data about knowledge and skills.

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.
Letβs 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 studentsβ 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 teachersβ 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, itβs important to have clear, objective rules to ensure you count
the same thing consistently.
For example, letβs say youβre collecting data on how often teachers have tech problems
β does an internet connection issue count, or will you only include problems that are
within the teacherβs 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 donβt 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 β what if you donβt 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 β 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 werenβt
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 donβt have any control over which variables to measure or
how to measure them, so the conclusions you can draw may be limited.
If youβre 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 youβll
use them.
