ANALISYS OF VARIANCE

ANALISIS DE LA VARIANZA

Analysis of variance (ANOVA I) to determine whether there are significant differences between treatments

Analisis de la varianza (ANOVA I) para determinar si existen diferencias significativas entre tratamientos


df sum_sq mean_sq F PR(>F)
Treatment 5 2668.83 533.77 34.7 3.18e-17
Residual 66 1015.17 15.38





df: degree of freedom, ....., PR(>F): Probability of true hypótesis (no statistically significant difference)

[ Because the PR (p) is below 0.05, we can say that at least exist one treatment that is statiscally different ]



MULTIPLE COMPARASION TEST - TUKEY HSD

TEST DE COMPARACIÓN MÚLTIPLE

Tukey test HSD (Honestly Significant Difference) is done to compare between different treatments together.

Se realiza el test de Tukey HSD (Honestly Significant Difference) que permite comparar entre los diferentes tratamientos entre si.

reject column means that the two treatment are statiscally different between self.

 

[ We can see that exist statiscally difference between A,B and F (in the same static group) with more insect lives and the treatment C,D and E (in the same group) with less insects lives ]
