In ANOVA the Relative Contribution of a Factor X Is $$\omega ^ { 2 } x = \frac { S S _ { x } / d f _ { x } } { S S _ { e r r o r } }$$

question 73

Multiple Choice

In ANOVA the relative contribution of a factor X is calculated as ________.

• A) \[\omega ^ { 2 } x = \frac { S S _ { x } / d f _ { x } } { S S _ { e r r o r } }\]
• B) \[\omega ^ { 2 } x = \frac { S S _ { x } - \left( d f _ { x } \times M S _ { \text {crror } } \right) } { S S _ { \text {total } } + M S _ { \text {crror } } }\]
• C) \[\omega ^ { 2 } x = \frac { \left( S S _ { x 1 } + S S _ { x 2 } + S S _ { x 1 x 2 } \right) / d f _ { x 1 } } { S S _ { \text {total } } + M S _ { \text {error } } }\]
• D) \[\omega ^ { 2 } x = \frac { S S _ { x } / ( c - 1 ) } { S S _ { c r r o r } / ( N - c ) }\]

Definitions:

Symbol

Graphical representations used in technical drawings to convey information about the part or assembly quickly and clearly.

Total Runout

Measurement that reflects the total variation a cylindrical or spherical object’s surface has when rotated about an axis.

Runout Tolerances

Specifications that limit the amount a mechanical part may deviate from a perfect circular path during its rotation.

Datum Axis

An imaginary line or axis on a part defined from a datum surface, serving as a reference for measuring and orienting the part.
