Most Important Factors

The primary goal of this experiment was to identify the most
important factors in maximizing the sonoluminescent light
intensity.
Based on the preceding graphical analysis, we make the
following conclusions.
 Four factors and three groups of 2factor interactions are
important. A rankorder listing of factors is:
 X2: Solute (effect = 78.6)
 X7: Clamping (effect = 78.1)
 X1*X3 (Molarity*pH) or
X2*X7 (Solute*Clamping)
(effect = 70.0)
 X1: Molarity (effect = 66.2)
 X3: pH (effect = 63.5)
 X2*X3 (Solute*pH) or
X4*X5 (Gas*Water Depth)
X1*X7 (Molarity*Clamping)
(effect = 63.5)
 X1*X2 (Molarity*Solute) or
X3*X7 (Ph*Clamping)
(effect = 59.6)
 Thus, of the seven factors and 21 2factor interactions,
it was found that four factors and at most seven 2factor
interactions seem important, with the remaining three factors
and 14 interactions apparently being unimportant.
