Question

Transcribed Image Text:**Complete ANOVA Table**
**Study Type:** Depression and Exercise
- **Groups Used:** 5
Depression scale ratings were between 1-100, given to all 1255 participants in the sample. Test at 5% significance.
**State Hypothesis, Test Statistic, P-value, and Conclusion.**
| Source | Sum of Squares | df | Mean Square | F-value | P-value |
|---------|----------------|------|-------------|---------|---------|
| Model | 68 | 4 | 17 | 14.86 | |
| Error | 185 | 1250 | 0.148 | | |
| Total | 253 | | | | |
**Explanation:**
- **Sum of Squares**: Represents the variation within the data.
- **df** (degrees of freedom): Number of values in the final calculation of a statistic that are free to vary.
- **Mean Square**: Calculated by dividing the sum of squares by the corresponding degrees of freedom.
- **F-value**: Ratio of the variance between the group means to the variance within the groups.
- **P-value**: Probability of obtaining the observed results assuming that the null hypothesis is correct. (Not provided here)
