Question

27. Which of the following could be concluded if a researcher rejects the null hypothesis in a test of significance for a Spearman’s rho?

	a.	that the variables are likely related in the population
	b.	that the relationship exists but its direction and strength are unknown
	c.	that no inference can be made about the relationship of the two variables in the population
	d.	that the relationship between the variables is negative

Answer 1

Solution:

Correct option is

that the relationship exists but its direction and strength are unknown.

Option b. is correct.

Explanation:

In the test of significance of Spearman’s rho ,

Null hypothesis is "there is no significant correlation "

Alternative hypothesis : "there is significant correlation "

When we reject the null hypothesis , we can conclude that "there is significant correlation "(maybe positive or negative , depend on the sign of r)

So , answer is

that the relationship exists but its direction and strength are unknown.
