摘要：Recent research into students¡¯ reasoning about variation refers specifically to notions
of distribution that emerge. This paper reports on research where written responses,
from tertiary introductory statistics students, were coded according to the level of
consideration of variation. A hierarchy of reasoning about distribution is proposed,
based on the notions of distribution that were evident in these responses. The
hierarchy reflects students¡¯ progression from describing key elements of distribution
to linking them for comparison and inference. The proposed hierarchy provides
researchers with an emerging framework of students¡¯ reasoning about distribution.
The research also highlights that educators need to be aware that, without a well
developed consideration of variation, students¡¯ ability to reason about distribution
will be hampered.
