Dr. Vance investigated whether there is an association between a patient's primary diagnosis (Generalized Anxiety Disorder or Major Depressive Disorder) and their preferred mode of therapy (in-person sessions or remote video sessions). He analyzed the data using a Chi-Square test of association (df=1df = 1df=1).
Dr. Vance formulated a two-tailed (non-directional) hypothesis and set his significance level at p≤0.05p \le 0.05p≤0.05. His calculated Chi-Square value was χ2=3.15\chi^2 = 3.15χ2=3.15.
Using the table of critical values below, determine whether Dr. Vance found a significant association between primary diagnosis and preferred mode of therapy.
| Significance level (ppp) for a two-tailed test | 0.10 | 0.05 | 0.01 |
|---|---|---|---|
| Critical value (df=1df = 1df=1) | 2.71 | 3.84 | 6.63 |
