In Conducting a Simple Linear Regression Analysis,an R² of 0

question 60

Essay

In conducting a simple linear regression analysis,an R² of 0.72 is obtained.This results in an F-value of 1027 and a p-value that is less than 0.0001.During a final check of the model,it is noticed that the distribution of the residuals is highly positively skewed.What does this mean?

Definitions:

Synchronous Speed

The speed at which the magnetic field in an AC motor rotates, directly related to the frequency of the power supply and the number of poles in the motor.

Alternating Current Frequency

The number of cycles per second in an alternating current (AC) waveform, typically measured in hertz (Hz).

Revolutions Per Minute

The unit of measure for rotational speed, indicating the number of full rotations completed by an object in one minute.

Power Triangle

A graphical representation in electrical engineering that shows the relationship between real power, reactive power, and apparent power in an AC circuit.
