Hypotheses are testable explanations of a problem, phenomenon, or observation.

  • Both quantitative and qualitative research involve formulating a hypothesis to address the research problem.
  • Hypotheses that suggest a causal relationship involve at least one independent variable and at least one dependent variable in other words, one variable which is presumed to affect the other.
  • An independent, variable is one whose value is manipulated by the researcher or experimenter.
  • A dependent variable is a variable whose values are presumed to change as a result of changes in the independent variable.
