QUALITATIVE AND QUANTITATIVE RESEARCH
What is to be observed?
• Quali: Qualities, behavior, complexities
• Quanti: Quantities, Scales, measurement
Purpose
• Quali: To understand or interpret social
interactions
• Quanti : To test hypothesis, look at cause and
effect and make predictions
Group Studied
• Quali: smaller and not randomly selected
• Quanti: larger and randomly selected
Types of data collected
• Quali: words, images or objects
• Quanti: numbers and statistics
Types of Questions asked
• Quali: Why? , How?
• Quanti: How many? , What?
Forms of data collected
• Quali: Qualitative data such as open-ended
responses, interviews, participants
observations, field notes and
reflections
• Quanti: Quantitative data based on precis
measurement using structured and validated
data collection instruments.
Strength
• Provide more detailed
information to explain
complex issues
• Multiple methods for
gathering data on
sensitive subjects.
• Data collection is usually
cost efficient.
• Issues can be examined
in detail and in depth.
Limitations
• Time consuming during
interviewing process and
intensive category
process.
• Rigor is more difficult to
maintain, assess, and
demonstrate.
Strength
Results in quantitative
research are less detailed.
Data gathering in
quantitative research is
efficient and requires less
effort.
Data gathering in
quantitative research is
fast and easier.
Limitations
In quantitative research
there is a possibility of an
