and Correct Detailed Answers Already Graded A+
Is the slope of the regression line the same as the regression coefficient? -
CORRECT ANSWER-Yes
R-Square (R2) - CORRECT ANSWER-Measures the completeness of a
relationship in regression analysis.
Total Sum of Squares - CORRECT ANSWER-Overall summary of the variation in
the dependent variable.
Regression Sum of Squares - CORRECT ANSWER-The component of the total
sum of squares that we pick up by knowing the independent variable.
Error Sum of Squares - CORRECT ANSWER-The component of the total sum of
squares that is not explained by the regression equation.
R2 - CORRECT ANSWER-Regression Sum of Squares/Total Sum of Squares
, Adjusted R-Square - CORRECT ANSWER-Often lose to but always less than
regular R-Square.
Dummy Variable - CORRECT ANSWER-Variable for which all cases falling into a
specific category assume the value of 1 (presence). Cases not falling into that
category assume a value of 0 (absence).
Multiple Regression - CORRECT ANSWER-Isolates the effect of one
independent variable on the dependent variable while controlling for the effects
of other independent variables.
Partial Regression Coefficient - CORRECT ANSWER-Estimates the mean change
in the dependent variable for each unit change in the independent variable.
Test of Statistical Significance - CORRECT ANSWER-Decides whether an
observed relationship between an independent and dependent variable exists in
the population.
Measure of Association - CORRECT ANSWER-How well the independent
variable works in explaining the dependent variable.
