Metodology of investigation
Shared elements and differences
Shared elements
Data collection through measurement
Statical analysis
Hypothesis-driven frameworks
Differences
Quantitative focuses on causality and control
Correlational focuses on variable relationships without manipulation
Correlational research
Definiton
Analyzing associations between variables
Characteristics
No manipulation of variables
Positive/negative correlation
Positive
Both variables increase or decrease together
Negative
One increases while the other decreases
No causal claims
While it identifies associations, it does not establish cause-effect relationships
Uses prediction and identifying relationships
Multiple variables
Often involves analyzing multiple variable pairs within a single study
Quantitative Research
Definition
Collects data to test hypotheses
Numerical measurement
statistical analysis
Identify patterns and validate theories
Characteristics
Measurement and estimation
Focuses on measuring and estimating the magnitude of phenomena
How often they occur and their intensity
Specific research problem
Begins with a correct defined and concrete research problem
Use of hypotheses
Formulates hypotheses derived from theoretical frameworks
Data Collection
Standardized, systematic measurement methods to ensure objectivity and replicability
Control and causality
Aims to control variables and identify causal relationships
Reducing uncertainty and minimizing errors
