Quantitative research designs

• Types of Quantitative Research Designs

  • Descriptive Research
  • Experimental Research
  • Correlational Research
  • Quasi-Experimental Research
• Descriptive Research


  • Utilized to describe characteristics, averages, trends, etc.
  • Variables are measured without influencing them
• Experimental Research


  • Designed to test causal relationships
  • Involves manipulating an independent variable and observing its impact on a dependent variable
  • Subjects are randomly assigned to groups
  • Typically conducted in a controlled environment like a laboratory
• Correlational Research


  • Utilized to examine the relationship and strength of association between variables
  • Variables are measured without influencing them
• Quasi-Experimental Research


  • Aims to test causal relationships
  • Similar to experimental design but lacks random assignment
  • Often involves comparing outcomes of pre-existing groups
  • Frequently conducted in a natural setting
