Analyzing Quantitative Data: Inferential Statistics

Cards (4)

  • Inferential statistics, which are based on the laws of probability, allow researchers to make inferences about a population based on data from a sample
  • The null hypothesis states that no relationship exists between research variables, and that any observed relationship is due to chance
  • If a null hypothesis is incorrectly rejected, this is a Type I error.
  • A Type II error occurs when a null hypothesis that should be rejected is ac cepted.
