Claim:
A statistical variable display apparatus comprising: a subgroup acquisition unit that acquires first-type subgroups and second-type subgroups from plural groups; an element acquisition unit that acquires first-type elements belonging to each first-type subgroup and second-type elements belonging to each second-type subgroup; a statistical variable acquisition unit that acquires a statistical variable between each of the first-type elements and each of the second-type elements; a first-axis-relating length determination unit that determines first lengths along a first axis, the first lengths being respectively allotted to the first-type subgroups, wherein the first lengths are variable; a second-axis-relating length determination unit that determines a second length, along a second axis, allotted to each second-type subgroup based on the first length allocated to a corresponding one of the first-type subgroups by setting a ratio between each of the first lengths and a respective one of the second lengths to be constant; and a three-dimensional display unit that displays, in a three-dimensional coordinate system having the first axis, the second axis and a third axis, the first-type elements of each first-type subgroup to be arranged within a region of each first-type subgroup that is arranged along the first axis to have the corresponding first length, the second-type elements of each second-type subgroup to be arranged within a region of each second-type subgroup that is arranged along the second axis to have the corresponding second length, and graphical representations of the acquired statistical variables along the third axis, each of the graphical representations of the acquired statistical variables being disposed correspondingly to one of the first-type elements arranged along the first axis and one of the second-type elements arranged along the second axis.
