    Question

    A researcher administered questionnaires to a group of randomly selected employees at a hospital. The questionnaires measured various socio-emotional aspects. The researcher determined the rank correlation between sociability and social dominance. She wants to test whether the rank correlation is significantly different from 0. Partial SPSS output is available:

    What do we know about the two-sided p-value of this test?


    1. FALSE: .005 < p < .01
    2. TRUE: .01 < p < .02
    3. FALSE: .02 < p < .05
    4. FALSE: .05 < p < .10

    Solution

    In Table B.7, at n = 30, we can look up the critical values. The p-value for such a critical value is exactly the significance shown above the column. The value .455 falls between the values .425 (.02) and .467 (.01).
