I Multiple Regression Is Used When Two or More Independent

question 6

Multiple Choice

i. Multiple regression is used when two or more independent variables are used to predict a value
Of a single dependent variable.
ii. The values of b1, b2 and b3 in a multiple regression equation are called the net regression
Coefficients. They indicate the change in the predicted value for a unit change in one X when the
Other X variables are held constant.
iii. Autocorrelation often happens when data has been collected over periods of time.

• 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:

Otoliths

Otoliths are small calcium carbonate crystals located in the inner ear that play a critical role in sensing gravity and linear acceleration, aiding in balance and spatial orientation.

Hair Cells

Sensory cells located in the inner ear, crucial for converting sound vibrations into neural signals for hearing and helping with balance.

Inner Ear

Part of the ear that contains the sensory organs for hearing and balance; contains the bony and membranous labyrinth.

Oscillation

A repetitive variation or fluctuation, typically in time, of a system about a central value or between two or more different states.
