A Brief Introduction to Biostatistics

Hypothesis testing



  • Another way of statistical inference in which we
    want to ask a question like

    • How likely is the mean systolic blood pressure
      from a sampled population (e.g. biomedical
      researchers) the same as those in the general
      population?

      • i.e. researchers = general?



    • Is the difference between 1 and 2 statistically
      significant for us to reject the hypothesis that their
      corresponding u 1 and u 2 are the same?

      • i.e. male = female?
