The Dynamics of Kea Behaviour and Interpretive Signage on Visitor ...

3.1.2 Holding Time <strong>and</strong> Holding Power
<strong>The</strong> mean Holding Time for individuals exposed to Sign Treatment 1 was 25.36 seconds
(SE=4.22) compared to 26.08 seconds (SE= 2.74) for Sign Treatment 2. Figure 7 is a
representation <strong>of</strong> the Holding Time <strong>of</strong> the two experimental sign treatments. On conducting an
independent samples t-test the difference between the two sign treatments was insignificant
(t= -0.143, df=182, P-value=0.887). <strong>The</strong> Holding Power for Sign Treatment 1 was 23%. <strong>The</strong>re
was a 1% increase in the Holding Power <strong>of</strong> the sign when the 3D casts were added (Sign 2).
Table 4 provides a summary <strong>of</strong> the performance measures <strong>of</strong> the two experimental sign
treatments.
