Conducting Research:
Surveys, Experiments
& Observations
Understanding Research Methods
Research methods are systematic approaches to collecting information and testing ideas.
Whether you're investigating human behavior, measuring program effectiveness, or
validating assumptions, choosing the right method is crucial for obtaining accurate,
reliable data.
Surveys
Questionnaire-based
method to gather
participant insights
and experiences on
specific topics
Observations
Qualitative approach
using human senses
to perceive and
document real-world
phenomena
Experiments
Controlled procedure
comparing groups
under different
conditions to test
hypotheses
Surveys: The Six-Step Process
Surveys are structured methods for gathering information about participant experiences,
opinions, and feedback through questionnaires. They can be administered personally, by
mail, or online, making them accessible and cost-effective for researchers.
01
Identify Participants
Determine your target population and select
representative participants for your study
02
Choose Survey Type
Decide between personal interviews, mail
surveys, or online questionnaires based on
your needs
03
Design Questions
Craft clear, unbiased questions using open-
ended or closed-ended formats
04
Distribute Survey
Deliver your survey to participants using your
chosen method
05
Analyze Responses
Review collected data, identify patterns, and
calculate relevant statistics
06
Write Results
Document findings in a clear, organized
report with conclusions and implications
Survey Question Types & Formats
Open-Ended Questions
Allow participants to provide detailed,
unrestricted responses in their own words.
These capture rich qualitative data and
unexpected insights but require more time
to analyze.
Example: "What challenges did you face using
this software?"
Close-Ended Questions
Present fixed response options (yes/no,
multiple choice, rating scales). These are
quick to complete and easy to analyze
quantitatively.
Example: "Rate your satisfaction: 1-5 scale"
Survey Advantages & Disadvantages
Advantages
• Easy to administer across large groups
• Cost-effective data collection
• Capable of gathering substantial amounts
of data
Disadvantages
• Participants may provide inaccurate answers
• Respondents may be uncomfortable
• answering honestly
• Non-responses can create data gaps and errors
Observation: Seeing the Bigger
Picture
Observation is a qualitative research method that
uses human senses to perceive and document
information directly from its actual source.
Researchers take descriptive notes of what they
witness, allowing them to understand social
phenomena and real-world contexts more deeply.
Unlike surveys that rely on self-report, observations
capture authentic behavior and provide insight into
the complete context of a situation. This method is
particularly valuable when studying human
behavior, social interactions, or complex
phenomena that resist simple questionnaires.
Observation Techniques for Data Collection
Documentation
Using printed documents, records, or existing
materials to gather observable information
and context
Video Recording
Recording participant behavior with permission,
allowing detailed review and analysis. Note:
Recording may cause participants to behave
uncomfortably
Written Descriptions
Taking detailed notes about participants,
environment, and situations as they occur.
Risk of missing details while note-taking
Photographs & Artifacts
Collecting visual evidence and physical objects
to document observable information and
environmental context
Observation Strengths & Limitations
Strengths
• Provides insight into complete, authentic situations
• Captures context and nuances missed by surveys
• Offers reliable information about natural behavior
• Allows researcher to become participant-observer
Limitations
• People change behavior when they know they're observe
• Researchers may miss important details
• Researcher misinterpretation of observations
• Requires significant time investment
Experimentation: Testing Under
Controlled Conditions
An experiment is a research procedure conducted
under controlled conditions to test cause-and-effect
relationships. Researchers randomly divide
participants into groups, apply different treatments,
and measure outcomes using dependent and
independent variables to determine what works
best.
Experiments differ fundamentally from surveys and
observations because they allow researchers to
actively manipulate variables and control
conditions. This makes experiments particularly
powerful for establishing causation and testing the
effectiveness of interventions or instructional
methods.
Types of Experiments
1
Natural Experiment
Conducted in a natural
setting where variables
are not controlled.
Researchers observe
naturally occurring
variations and their
effects, sacrificing control
for real-world
authenticity.
2
Controlled Experiment
Researcher maintains
strict control over
conditions and variables.
Compares an
experimental group
receiving treatment
against a control group
with no treatment or
standard treatment to
isolate effects.
3
Field Experiment
Combines elements of
natural and controlled
experiments. May involve
either controlled or
natural variables, but is
conducted in a real-world
setting rather than a
laboratory.
Experimental Advantages &
Challenges
Key Advantages
Experiments offer
researchers significant
control over variables,
enabling precise
measurement of cause-
and-effect relationships.
They effectively
determine which
methods, strategies, or
interventions work best
and provide valuable
insights into teaching
and learning
effectiveness.
Important Challenges
Researcher personal
bias can distort results.
Experiments may
produce artificial results
due to controlled
conditions that don't
reflect real-world
complexity. Additionally,
human variables can be
difficult to measure
precisely and
consistently across
conditions.
Avoiding Bias in Research
Regardless of which method you choose—surveys, observations, or experiments—awareness of
potential biases is essential for conducting credible research. Researchers must actively work to
minimize personal bias, ensure honest participant responses, and maintain objectivity throughout
data collection and analysis.
Design Neutral Questions
Avoid leading or suggestive language that might influence participant responses
Ensure Anonymity
Remove identifying information to encourage honest feedback and protect participants
Remain Objective
Maintain consistent procedures and don't let expectations influence data interpretation
Document Everything
Keep detailed records of methods, decisions, and procedures for transparency and replicabilit
Seek Peer Review
Have colleagues examine your research design and findings to catch potential biases
Remember: Quality research requires choosing the right method for your question, executing it
carefully, and remaining vigilant against bias throughout the process. By understanding these three
fundamental approaches, you'll be equipped to conduct meaningful research across many
