Objectives

• Objective of Validation phase is
• To decide whether the objective of the task has
  been achieved
• Based on formal conclusions
• And rigorous peer review

5
Compute Performance

• Reduced results in Synthesis
• Scientific Method stepwise refinement
• Performance metrics may need to be revised if
• Not suitable
• Do not validate hypothesis

6
Null Hypothesis

• Statement of hypothesis that refers to a single,
  unambiguous value
• Eg The average fuel efficiency of the new engine
  is 40 mpg

  new engine exceeds 40 mpg
