Central dogma of biostatistics:

Estimation and hypothesis testing

• Statistical estimation
  
  
  • Estimating population parameters based on
    sample statistics
  
  
  • Application of the “Confidence interval”
  
  
  
  


• Hypothesis testing
  
  
  • Testing certain assumptions about the population
    by using probabilities to estimate the likelihood of
    the results obtained in the sample(s) given the
    assumptions about the population
  
  
  • Application of “Test for statistical significance”
