Regression Analysis

Regressionanalysis is the measure of .......................relationship between variables

• nature

• independence

• cause and effect

• none of these

Correlation coefficientcis equal to ........................of regression coefficients.

• AM

• GM

• AVERAGE

• SUM

If $bxy$   is greater than 1 then 

 $byx$  is..................

• greater than 1
  

• less than 1
  

• equal to 1
  

• equal to -1
  

 

the range of regression coefficient is.................

•  $-\infty$  to 0
  

•  $-\ \infty\ \ to\ \ \infty$  

• -1  to     +1
  

•  $1\ to\ \infty$  

if r=0.5     $bxy$  =1   then  $byx$  =..................

 

if r=0.5       $byx$  =0.5 then   $bxy$  =.............

if     $bxy$  =2 and    $byx$  =0.5 then  r=...............

the term regression was introduced by....................

• R A Fischer

In a regression line of Yon X the variable Xis known as

• independent variables

• regressior

• explanatory variable

• all of the above

The regression line of Y on X is 5x-7y=10, then the regression coefficient of Y on X is

• $\frac{5}{7}$

• $\frac{7}{5}$

• $\frac{-7}{5}$

• $\frac{10}{7}$
