MCQs 1 on "REGRESSION AND CORRELATION"

These are MCQs 1 on "REGRESSION AND CORRELATION" Statistics. Practice MCQs to check your knowledge for Entrance examination like CSIR NET, BINC etc.

1. A process by which we estimate the value of dependent variable on the basis of one or more independent variables is called:

• Correlation
• Regression
• Residual
• Slope

2. The method of least squares dictates that we choose a regression line where the sum of the square of deviations of the points from the lie is:

• Maximum
• Minimum
• Zero
• Positive

3. A relationship where the flow of the data points is best represented by a curve is called:

• Linear relationship
• Nonlinear relationship
• Linear positive
• Linear negative

4. All data points falling along a straight line is called:

• Linear relationship
• Non linear relationship
• Residual
• Scatter diagram

5. The value we would predict for the dependent variable when the independent variables are all equal to zero is called:

• Slope
• Sum of residual
• Intercept
• Difficult to tell

6. The predicted rate of response of the dependent variable to changes in the independent variable is called:

• Slope
• Intercept
• Error
• Regression equation

7. The slope of the regression line of Y on X is also called the:

• Correlation coefficient of X on Y
• Correlation coefficient of Y on X
• Regression coefficient of X on Y
• Regression coefficient of Y on X

8. In simple linear regression, the numbers of unknown constants are:

• One
• Two
• Three
• Four

9. In simple regression equation, the numbers of variables involved are:

• 0
• 1
• 2
• 3

10. If the value of any regression coefficient is zero, then two variables are:

• Qualitative
• Correlation
• Dependent
• Independent
