Research methodology
Quantitative Research Approach and Its Main Characteristics
Uses numerical data
to analyze
Relationships
Between variables
Follows a predetermined research process
with specific steps.
Formulates hypotheses
before data collection
ests them using statistical methods.
Uses representative samples
To generalize findings to a larger population.
Focuses on numerical data
Wich can be
quantified
statistically analyzed.
Ensures findings can be verified
by repeating the study
with different samples.
Determines relationships between variables
using statistical techniques.
Comparative-Type Research and Its Main Characteristics
Compares multiple cases
to identify
patterns
trends
Differences
Can use
qualitative
quantitative
mixed-methods approaches
Uses various forms of data
historical records
surveys
Interviews
Can compare
individuals
groups
institutions
nations.
cultures
Levels of comparison
Includes micro-level
Individuals
Meso.level
Organizations
Macro-level
Societies
Uses theoretical perspectives
to interpret findings
Experiments and Experimental Design
The researcher changes one or more independent variables
to observe effects.
Participants are randomly assigned to experimental
control groups to reduce bias.
Control group and experimental
One group receives treatment
while the other does not
for comparison.
Measurements
are taken before
and after intervention
to assess changes.
Types of Experimental Designs
Pre-Experimental Designs
Basic exploratory experiments with limited control.
True Experimental Designs
Include randomization
control groups
strict conditions
Quasi-Experimental Designs
Lacks full randomization
allows causal inference in realworld settings.
