The study by Peter Nonacs, PhD Investigates:
Total sample size 1199 Ants
Size
Distance
Foraging Habits Data
11 Colony
Determine that there’s a relationship between distance travelled by ants and the worker class group
Samples were collected at varying distances using traps
Statistical Tests & Analyses
One Way Analysis of Variance
Assumption
Kruskal-Wallis
Normality Test: Failed
Multiple Comparison Procedure

Results
H = 38.918 with 5 degrees of freedom. (P = <0.001)
The Dunn’s multiple comparison analysis produce a significant difference for only one comparison (40-43 vs 30) with Q=4.221 and P < 0.05, while the others were insignificant.
Conclusion
There is a significant difference in the distance travelled among the varying worker classes.
Thus, there is a relationship between the worker class and the foraging distance of the thatch ant.
