3.4.5 Flea biased parasitism on rodent’s sex and weight
We found statistical significant difference in flea abundance between
male and female rodents (Wilcoxon rank sum test W = 9158.5, p =
.009) with small magnitude of effects size (r= .153) (Rules: funder
2019). The median weight of these two sexes was 40.1g (IQR= 25.3g) and
39.4g (IQR= 23g) for male and female rodents respectively and were not
statistically significant different (W = 10140, p = .54).
Correspondingly, we found statistical significant correlation between
flea abundance and rodent’s weight with Spearman’s rank correlation
coefficients (R = .17, S = 34176 and p <
.05) indicating weak positive correlation (fig. 4 A) .
