About Lesson

Significance of replication in experiments

  • Provides estimate of an experimental error
  • Improve precision of experiment
  • Increase scope of inference of experiment
  • To control effect of error variance

 

Significance of randomization in experiment

  • To have valid estimate of experimental error
  • Remove bias
  • Protect against the external uncontrollable factors
