Question

THE EQUATION OF THE REGRESSION LINE IS Y = a+ bX. MATCH THE FOLLOWING SYMBOLS TO THE DESCRIPTION TO THE RIGHT.

1.      DENOTES THE VARIABLE PLOTTED ON THE HORIZONTAL AXIS AND CALLED THE VARIABLE.THE EXPLANTORY OR INDEPENDENT VARIABLE..

2.      . Denotes the variable plotted on the vertical axis and is called the response OR DEPENDENT VARIABLE.

3.      THE RGRESSION RESULT = THE CHANGE IN Y FOR A CHANGE IN X +1 AND CALLED THE SLOPE

4.      THE PROPORTION OF THE VARIABILITY OF Y THAT IS EXPLAINED BY ACCOUNTABLE TO X.

5.       THE STRENGTJ AMD DIRECTION OF THE LINEAR RELATIONSHIP BETWEEN X AND Y

6.      THE REGRESSION RESULT = ELEVATIONION OF THE LINE AT X=0 AND CALLED THE INTERECPT.

______ a

______ R

_______ X

_______ b

_________ R2

________ y

Answer 1

  Y= a + bX

dependent variable= intercept + slope* dependent variable

1) DENOTES THE VARIABLE PLOTTED ON THE HORIZONTAL AXIS AND CALLED THE VARIABLE.THE EXPLANTORY OR INDEPENDENT VARIABLE.- X

2) Denotes the variable plotted on the vertical axis and is called the response OR DEPENDENT VARIABLE. - Y

3) THE REGRESSION RESULT = THE CHANGE IN Y FOR A CHANGE IN X +1 AND CALLED THE SLOPE- b

4) PROPORTION OF THE VARIABILITY OF Y THAT IS EXPLAINED BY ACCOUNTABLE TO X.- R²

5) THE STRENGTH AMD DIRECTION OF THE LINEAR RELATIONSHIP BETWEEN X AND Y- R

6) THE REGRESSION RESULT = ELEVATION OF THE LINE AT X=0 AND CALLED THE INTERCEPT.- a
