The test statistics are the paired sample Student's t, the nonparametric
Sign test (M) and the nonparametric Wilcoxon Signed Rank (S).
No colonies showed significant bottlenecks under the
sign test. UCO, West and East Arcadia showed mode shifts across both sampling schemes.

An issue with the
sign test relates to the fact it does not account for the size of each effect.
There was a significant improvement in the Wexner score post-procedure (12.5 pre-injection, 7.9 post-injection; p=0.0005, Wilcoxon rank
sign test, Figure 2).
Animal evinced pain on palpating the left stifle joint and positive for the cranial drawer
sign test and anterior tibial thrust which was suggestive of cranial cruciate ligament rupture, accordingly surgical stabilisation using both medial and lateral retinacular imbrication technique was planned.
This result is further illustrated by the results from a
sign test (Pesaran and Timmermann [19]).
We evaluated potential under- or overstatement of duration using a
sign test. The
sign test is a test of the difference in medians.
