QUANTI-tative Study Designs

Selection of the best qualified study design answers your research question and objectives accurately and reliably

What does a good research study design heavily rely on?

Finalized and refined research question and specific objectives

What should researchers have before selecting a study design?

One person, experience, or event in depth

What do individualized study designs focus on?

Analyze larger populations or multiple studies to identify patterns

What do generalized study designs focus on?

To generalize findings from a sample to a larger population

What is one purpose of generalized study designs?

Exploratory vs Causal

What are the two main objectives-based classifications of study designs?

Explore poorly understood problems to gain insight and familiarity

What is the goal of exploratory studies?

Test hypotheses to establish associations or cause-effect relationships

What is the goal of causal studies?

Observational vs Experimental

What are the two main classifications based on researcher intervention?

Data without intervening or manipulating variables

What defines observational studies?

Active manipulation of interventions or treatments, often with randomization

What defines experimental studies?

Descriptive vs Analytical

What are the two main classifications based on data analysis?

Present data to describe populations or variables

What is the goal of descriptive studies?

Statistics to compare groups, test effects, and measure associations
