Choose orthogonal table

• Proposed standard methodchoose the first level
  of factor A as a virtual level,
• So we can choose L16(45)which has equal level and
  just conduct 16 tests.

• The best combination of apple juice is A3B4C4An
  apple and a half, five teaspoons of sugar, four
  tablespoons of vinegar.

25

• The order of the significant factors is ABC,
  which means the greatest impact on the taste of
  the apple juice is the number of apples,
  followed by sugar,and vinegar is the least

• By analyzing the significance of each factor
  level, considering the low-cost, easy to operate
  and other factors, we get the best combination of
  apple juice A3B4C1-- by means of analysis of
  variance.

29

• Error e1.3
• The personal preferences, for instance some
  people prefer sweet, but some people prefer sour

30

• Other factors that may affect the taste of the
  apple juice that we do not know
• Because of the existence of errors in personnel,
  raw materials, environment, these can lead to
  large errors in the final results

Summary

• As an undergraduate, through this test, our
  greatest achievement is not the results of the
  experiment itself, but rather learn how to apply
  the knowledge learned into practice.For
  companies,adoping this method can both save cost
  and meet the consumer demand.
