ANOVA
Source of Variation | df | Sum of Squares | Mean Square | F |
---|---|---|---|---|
Regression | 3 | 1,004,346.771 | 334,782.257 | 5.96 |
Residual | 26 | 1,461,134.596 | 56,197.48445 | |
Total | 29 | 2,465,481.367 |
Coefficients | Standard Error | t-Stat | p-value | |
---|---|---|---|---|
Intercept | 784.92 | 322.25 | 2.44 | 0.02 |
Service | 9.19 | 3.20 | 2.87 | 0.01 |
Gender | 222.78 | 89.00 | 2.50 | 0.02 |
Job | −28.21 | 89.61 | −0.31 | 0.76 |
