The Coefficient of Determination R², a Measure of the Goodness

question 43

True/False

The coefficient of determination r², a measure of the goodness of fit of the estimated regression equation, is the ratio of the explained variation in y to the total variation in y, and takes on values between 0 and 1.

Definitions:

Current Path(s)

The route that electrical current flows through in a circuit, which may include components like resistors, capacitors, and inductors.

Total Resistance

The overall opposition to electric current flow in a series circuit, calculated by summing the resistance values of all components.

Series Circuits

Electrical circuits in which components are connected end-to-end, so that there is only one path for current flow.

Voltage Drop

The reduction in voltage in a part of a circuit due to resistance or impedance, seen in the difference in voltage across a component or conductor.
