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) All statements are false

Multiple regression involves multiple independent variables predicting a dependent variable. The coefficients (b1, b2, b3) represent changes in the dependent variable for unit changes in independent variables, holding others constant. Autocorrelation is common in time series data.
