2x2 matrix
A two by two matrix is a useful tool for initial sorting of
qualitative data.
The axes should be chosen so that, e.g., the data with the
most desirable characteristics will fall into the upper left
quadrant and the least desirable in the lower right quadrant.
While groups may be unable or unwilling to assign absolute values
to qualitative data, they usually find it relatively easy to
come to a consensus as to which quadrant something belongs in.
Generally, the two by two matrix is a useful tool for categorising
things that can be reduced to two simple variables, particularly
when quantitative information is unavailable and qualitative
judgements must be made.
It enables a rapid clustering (or separating) of information
into four categories, which can be defined to suit the purpose
of the exercise. It is particularly useful with groups as a way
of visibly plotting out a common understanding or agreement of
a subject. |
