Fig 4. Acceptability of alternative housing systems when confronted with different trade-off situations.

Split 1: n = 520; split 2: n = 518; displayed are means and standard deviations. Rating on a 7-point Likert scale from 1 = completely disagree, to 4 = partly/partly, to 7 = totally agree. Comparison of means within a split sample using t-test for dependent samples. Different letters indicate significant differences (p ≤ 0.05) between advantages/disadvantages within a housing system, and same letters indicate no significant differences (p > 0.05). Comparison of means between housing systems revealed significant differences between the same advantages/disadvantages (p ≤ 0.001) but are not marked in the figure.
