**Output 1. Descriptive Results**

**The categories in the Factor Group**

**Descriptive statistics by group**

**Explanations**

- The band inside the box is the median
- The box measures the difference between 75th and 25th percentiles
- Outliers will be in red, if existing

**Output 2. ANOVA Table**

**Explanations**

- DF
_{Factor}= [number of factor group categories] -1 - DF
_{Residuals}= [number of sample values] - [number of factor group categories] - MS = SS/DF
- F = MS
_{Factor}/ MS_{Residuals} - P Value < 0.05, then the population means are significantly different among factor groups. (Accept alternative hypothesis)
- P Value >= 0.05, then there is NO significant differences in the factor groups. (Accept null hypothesis)

*In this example, smoking groups showed significant, so we could conclude that FEF were significantly different among the 6 groups. *

**When P < 0.05,** if you want to find which pairwise factor groups are significantly different, please continue with **Multiple Comparison**
