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.

Units of the values are millivolts (mV).
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 ).
Thompson's sign test
is not very obvious in some patients with AATR for the intact plantar tendon or more proximal rupture.
We evaluated potential under- or overstatement of duration using a sign test
. The sign test
is a test of the difference in medians.
