If the correlation coefficient is -0.1, then we would expect to make:

	a) good predictions from a regression line rising from left to right.
	b) poor predictions from a regression line rising from left to right.
	c) poor predictions from a regression line falling from left to right.
	d) good predictions from a regression line falling from left to right.

Answer 1

Answer #1

If Correlation Coefficient:

± 1,perfect Correlation

between ± 0.50 and ± 1,Strong Correlation

between ± 0.30 and ± 0.49, medium correlation.

below ± 0.29, small correlation.

0, No correlation

Ans:c) poor predictions from a regression line falling from left to right
