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) .
