part 1

• Quantitative Research Design are empirical, straightforward, and can test their reliability and validity.
• Quantitative Research Design may vary in terms of the following:

  • the intent
  • use of manipulation
  • procedures used
• Experimental Research Design aims to find out whether an intervention considered as the independent variable has an effect on a dependent variable.
• Experimental Research Design must contain the following elements:

  • treatment or intervention
  • controlling extraneous variables
  • randomization of participants
• Quasi-Experimental Design requires the independent variable to be manipulated but it lacks a key element of an experimental design, which is randomization.
• Correlational Design studies the association between two variables but does not tell about its causality.
• Positive Correlation is when one variable increases, so is the other variable
