I the Multiple Standard Error of Estimate Measures the Variation

question 18

Multiple Choice

i. The multiple standard error of estimate measures the variation about the regression plane when two independent variables are considered. ii. The multiple coefficient of determination, R², reports the proportion of the variation in Y that is not explained by the variation in the set of independent variables.
iii. The coefficient of multiple determination reports the strength of the association between the dependent variable and the set of independent variables.

• A) (i), (ii), and (iii) are all correct statements.
• B) (i) and (ii) are correct statements but not (iii).
• C) (i) and (iii) are correct statements but not (ii).
• D) (ii) and (iii) are correct statements but not (i).
• E) (i), (ii), and (iii) are all false statements.

Definitions:

Basic Dimension

A numerical value that describes the theoretically exact size, profile, orientation, or location of a feature without any allowance for tolerances.

Dimensions Locating

The process of defining and marking the exact locations of features on manufactured parts, crucial for their proper assembly and function.

Target Areas

Specific regions designated for attention or action in a project or on a drawing.

Datum Feature

A reference point, axis, or plane from which dimensions are measured, providing a starting point for the geometric control of a part.
