Noah obtained a calculated χ2 \chi^2\,χ2 value of 4.02 with df=1df = 1df=1 for his study investigating the association between coaching style and athletic performance level.
Using the table of critical values below, explain whether Noah's results are significant for a two-tailed (non-directional) hypothesis at the p≤0.05 p \le 0.05\,p≤0.05 level of significance.
| Level of significance for a two-tailed test | p≤0.05p \le 0.05p≤0.05 | p≤0.01p \le 0.01p≤0.01 |
|---|---|---|
| Critical value (df=1df = 1df=1) | 3.84 | 6.64 |
