MCQs 3 on "REGRESSION AND CORRELATION"

These are MCQs 3 on "REGRESSION AND CORRELATION" Statistics. Practice MCQs to check your knowledge for Entrance examination like CSIR NET, BINC etc.

1. In the regression equation Y = a+bX, the Y is called:

• Independent variable
• Dependent variable
• Continuous variable
• None of the above

2. In the regression equation X = a + bY, the X is called:

• Independent variable
• Dependent variable
• Qualitative variable
• None of the above

3. In the regression equation Y = a +bX, a is called:

• X-intercept
• Y-intercept
• Dependent variable
• None of the above

4. The regression equation always passes through:

• (X, Y)
• (a, b)
• X ,Y
• X , Y

5. The independent variable in a regression line is:

• Non-random variable
• Random variable
• Qualitative variable
• None of the above

6. The graph showing the paired points of (Xi, Yi) is called:

• Scatter diagram
• Histogram
• Historigram
• Pie diagram

7. When regression line passes through the origin, then:

• Intercept is zero
• Regression coefficient is zero
• Correlation is zero
• Association is zero

8. When bXY is positive, then byx will be:

• Negative
• Positive
• Zero
• One

9. The correlation coefficient is the_______of two regression coefficients:

• Geometric mean
• Arithmetic mean
• Harmonic mean
• Median

10. When two regression coefficients bear same algebraic signs, then correlation coefficient is:

• Positive
• Negative
• According to two signs
• Zero
