When Performing a Rank Correlation Test, One Alternative to Using $r _ { S } = \pm \sqrt { \frac { t ^ { 2 } } { t ^ { 2 } + n - 2 } }$

question 104

Multiple Choice

When performing a rank correlation test, one alternative to using the Critical Values of Spearman's Rank Correlation Coefficient table to find critical values is to compute them using this approximation: $r _ { S } = \pm \sqrt { \frac { t ^ { 2 } } { t ^ { 2 } + n - 2 } }$
where $t$ is the $t$ -score from the $t$ Distribution table corresponding $t$ n $- 2$ degrees of freedom. Use this approximation to find critical values of $\mathrm { r } _ { \mathrm { S } }$ for the case where $\mathrm { n } = 11$ and $\alpha = 0.01$ .

• A) \(\pm 0.735\)
• B) \(\pm 0.411\)
• C) \(\pm 0.685\)
• D) \(\pm 0.726\)

Definitions:

Observable Behaviors

Actions or reactions of an individual in various situations, which are visible and measurable by others or through instruments.

Intervening Variables

Factors within a study that mediate the relationship between the independent and dependent variables, potentially affecting the outcome.

Negative Reinforcement

a behavior modification technique where the removal of an undesirable or unpleasant outcome after the display of a desired behavior increases the likelihood of the behavior being repeated.

Spontaneous Recovery

The reappearance of a previously extinguished conditioned response after a period without exposure to the conditioned stimulus.
