Using this Tukey's pot-hoc test (attached picture), which values are significant, p < 0.05? How do I interpret these results into an APA sentence?

Transcribed Image Text:The table presented is titled "Post Hoc Comparisons - SLEEPDEP" and presents the results of statistical comparisons between different groups based on hours of sleep deprivation. The columns in the table are labeled as follows:
- **Groups Compared**: Shows pairs of hours being compared (e.g., 10, Hours vs. 15, Hours).
- **Mean Difference**: Indicates the calculated mean difference between the two groups.
- **SE (Standard Error)**: Provides the standard error of the mean difference.
- **t**: Represents the t-value from the t-test conducted for the comparison.
- **Ptukey**: Displays the p-value adjusted by the Tukey's test for multiple comparisons.
The comparisons are as follows:
1. Between 10 and 15 hours:
- Mean Difference: 3.167
- SE: 1.846
- t: 1.715
- Ptukey: 0.342
2. Between 10 and 25 hours:
- Mean Difference: 5.667
- SE: 1.846
- t: 3.069
- Ptukey: 0.028
3. Between 10 and 5 hours:
- Mean Difference: -0.667
- SE: 1.846
- t: -0.361
- Ptukey: 0.983
4. Between 15 and 25 hours:
- Mean Difference: 2.500
- SE: 1.846
- t: 1.354
- Ptukey: 0.541
5. Between 15 and 5 hours:
- Mean Difference: -3.833
- SE: 1.846
- t: -2.076
- Ptukey: 0.195
6. Between 25 and 5 hours:
- Mean Difference: -6.333
- SE: 1.846
- t: -3.431
- Ptukey: 0.013
Key observations:
- Significant differences (p < 0.05) are noted between 10 vs. 25 hours and 25 vs. 5 hours, given the Ptukey values of 0.028 and 0.013, respectively.
