Research Design Types and Methodologies

Ex post facto design looks at the possible causes of a phenomenon before it occurs.

Descriptive research aims to manipulate variables to observe their effects.

Quasi-experimental design has higher validity compared to experimental design due to random selection and assignment of subjects.

Experimental design provides more conclusive results than correlational research.

Variables in quantitative research cannot be manipulated or controlled.

True or False: Experimental research allows researchers to manipulate variables in order to identify cause-effect relationships.

True or False: Nonexperimental research relies solely on correlations, surveys, or case studies and cannot establish cause-effect relationships.

True or False: Descriptive research aims to describe a situation or area of interest subjectively without relying on facts or accuracy.

True or False: Correlational research investigates the potential cause-and-effect relationships between variables.

True or False: Quasi-Experimental method allows for full control and manipulation of all relevant variables similar to a true experimental method.
