This result is not unexpected and simply means that the levels of compliance differed at the different buildings (with buildings l-6 having proportions of compliance and totals as follows: 0.88 (N=216), 0.77
(N=79), 58 (N=61), 0.87 (N= 159) 56 (N= 136) and
0.60 (N= 140) respectively. This building effect might
be due to multiple factors such as the varied
configuration of the buildings and the characteristics of
the individuals who frequent the locations. It is also
not surprising to find that different numbers of people
used the elevators at the different locations. The
buildings were of different sizes, used in different ways
(academic and residential), and some had more than
one elevator. Thus, it is reasonable to expect that
elevator usage differs across buildings.
