Descriptive design

Observing a phenomenon as it happens naturally; no experiment or hypothesis needed.

Correlational design

Finding relationships between variables; not about cause and effect.

Quasi-experimental design

Trying to find cause-and-effect, but no random subject assignment.

Experimental design

Finding cause-and-effect links with random subject assignment.

Study Notes

Types of Quantitative Research

  • Descriptive Design: Aims to describe a phenomenon as it naturally occurs. It observes without manipulation, and doesn't start with a hypothesis.

  • Example: Determining student academic performance during modular distance learning.

Types of Quantitative Research (cont.)

  • Correlational Design: Examines relationships between two or more variables. It identifies correlations but does not prove cause and effect.

  • Example: Relationship between physical activity and student academic achievement.

Types of Quantitative Research (cont.)

  • Quasi-Experimental Design: Establishes cause-and-effect relationships, but subjects are not randomly selected or assigned.

  • Example: Effect of smoking on the respiratory system.

Types of Quantitative Research (cont.)

  • Experimental Design: Establishes cause-and-effect relationships by randomly assigning subjects to experimental and control groups.

  • Example: Effect of plant growth enhancers on plant growth. This shows a clear experimental and control group.
