A correlational non-experimental design is a type of research design that involves measuring the relationship between two or more variables without manipulating them. This type of design is used to determine if there is a relationship between variables, but it does not establish causation. Researchers collect data on the variables of interest and analyze the strength and direction of the relationship between them using statistical techniques such as correlation analysis. This design is often used in observational studies or when it is not possible or ethical to manipulate variables in an experiment.

Correlational Non-Experimental Design
A correlational non-experimental design is a type of research design where the researcher investigates the relationship between two or more variables without manipulating or controlling any of them. Instead, the researcher simply observes and records the自然occurring variations in the variables.
Characteristics:
- Observational: Researchers observe and measure the variables without actively manipulating or controlling them.
- Naturalistic: Variables are studied in their natural settings, with minimal intervention from the researcher.
- Cross-sectional: Data is collected at a single point in time.
- Correlation: Relationships between variables are assessed, but causality cannot be established.
Advantages:
- Can investigate relationships between variables in real-world settings.
- Can provide insights into complex phenomena that cannot be easily manipulated or controlled.
- Less expensive and time-consuming than experimental designs.
Disadvantages:
- Cannot establish causality (i.e., whether one variable causes changes in another).
- May be confounded by other variables that are not measured or accounted for.
- Results may be less precise or generalizable than those from experimental designs.
Applications:
Correlational non-experimental designs are commonly used in:
- Psychology: Investigating relationships between personality traits, cognitive abilities, and behaviors.
- Sociology: Studying relationships between social factors, such as income, education, and crime.
- Health research: Examining associations between lifestyle factors, environmental exposures, and health outcomes.
- Market research: Exploring relationships between product attributes, advertising, and consumer behavior.
Examples:
- Investigating the relationship between stress levels and academic performance in students.
- Examining the correlation between social media use and mental health outcomes.
- Studying the association between air pollution and respiratory illnesses.
- Analyzing the relationship between income and access to healthcare.
