Study Notes
Quantitative Research Design Overview
- Quantitative research designs are empirical, straightforward, and can test reliability and validity.
- Quantitative designs vary in intent, use of manipulation, and procedures used.
- Research design can be easily identified from a journal article abstract.
Types of Quantitative Research Design
Experimental Design
-
Aims to determine if an intervention (independent variable) affects an outcome (dependent variable).
-
Crucial elements include:
- Treatment or intervention
- Control of extraneous variables
- Randomization of participants
-
Example: A study using a new curriculum (independent variable) and measuring reading comprehension level (dependent variable), randomly assigning participants to different groups to test the effect of the new curriculum on comprehension.
Quasi-Experimental Design
- Similar to experimental designs but lacks randomization. Researchers manipulate the independent variable, but participants are not randomly assigned.
- Still useful for investigating causal relationships in situations where randomization is not possible.
- Example: Comparing reading comprehension in one section using a new curriculum and another section not using the new curriculum.
Correlational Design
- Investigates the relationship between two variables, but does not establish causality.
- Example: Examining the relationship between stress level and academic performance.
Descriptive Design
-
Seeks to describe naturally occurring phenomena or characteristics of a specific population.
-
Example: Surveys, demographic research (describing basic life events), or epidemiological research (studying disease patterns).
-
Three common types include survey, demographic, and epidemiological research.
-
Survey research explores trends in characteristics of groups.
-
Demographic research describes basic life events.
-
Epidemiological research studies disease and health patterns
-
Descriptive designs explain different patterns of information about a target population.
Additional Study Points
- Factors to consider when using quantitative research design should be explored.
- Positive correlations show that as one variable increases, so does the other.
- Negative correlations exist when one variable increases, and the other decreases.
