- Relationship between correlation coefficient and coefficient of determination is that
- If the coefficient of determination is equal to 1, then the correlation coefficient :
- The rank correlation coefficient of a debating contest involving 10 participants was calculated as 0.6. However, it was later discovered that the difference in the ranks of some participants was read as 8 instead of 3. Find the correct correlation coefficient:
- If there is a very strong correlation between two variables then the correlation coefficient must be:
- If the sum of squares of the rank differences of 10 pairs of values is 30, find the correlation coefficient between them.
- The coefficient of correlation between the regression coefficients is:
- The Correlation coefficient between two variables is the………………..of their regression coefficients.
- The value of the correlation coefficient lies between
- Let the coefficient of determination computed to be 0.39 in a problem involving one independent variable and one dependent variable. This result means that:
- In a bivariate sample, the sum of squares of differences between marks of observed values of two variables is 33 and the rank correlation between them is 0.8. Find the number of pairs of observations:
