WHAT IS QUALITATIVE DATA? 21<br />
home; where we work, not play. For most purposes, we do not bother to make rigid<br />
and complete distinctions, so long as we can make some reasonably rough and ready<br />
decisions about what ‘belongs’ where. When Eve said ‘here’s an apple’ to Adam, she<br />
wanted him to recognize it for what it is: an apple. She named the fruit an ‘apple’ to<br />
signify that it has certain characteristics: according to my dictionary it is a ‘rounded<br />
firm edible juicy fruit of a tree of the genus Malus’ or ‘any of various similar fleshy<br />
many-celled fruits’. ‘Edible and juicy’ was probably enough for Adam. The category<br />
‘apple’ signifies these characteristics, more or less vaguely defined. The categories we<br />
use may be vaguely defined, but we don’t worry unduly so long as they ‘work’ for<br />
us. We want to know that the apple is juicy and edible, not dry and inedible.<br />
Our categories can be ‘fuzzy’ and overlapping. For most purposes, we may think<br />
of schools as a set of purpose-built buildings. But a school can also double as a<br />
community centre, a sports facility, and during elections as a voting centre. For<br />
parents educating their children at home, part of the house may function as ‘school’<br />
for part of the day. And there may be little agreement on what a school does. For<br />
some it may an institution for imparting skills and certifying achievement, for<br />
others it may be little more than a giant child-minding institution. A concept can<br />
convey very different connotations. So the distinctions we draw in describing<br />
something as a school may vary according to context.<br />
Categorizing at this level therefore involves an implicit and loosely defined<br />
classification of observations. Categorizing brings together a number of observations<br />
which we consider similar in some respects, by implied contrast with other<br />
observations. But the boundaries are not tightly defined, and we are typically vague<br />
about the precise respects in which we differentiate our observations. This means<br />
that in assigning something to one category, we do not automatically exclude it from<br />
others. We discount other possibilities, rather than exclude them altogether. For<br />
example, in counting certain observations as ‘schools’, we discount other categories<br />
such as ‘community centres’, but we do not explicitly exclude them as possibilities.<br />
So counting how many schools there are tells us nothing about how many<br />
community centres there may be. In this sense, our categories are inclusive rather<br />
than exclusive. We focus on whether or not to include an observation within the<br />
category (e.g. to count it as a school) rather than whether in doing so we exclude the<br />
observation from other categories. In Figure 2.3, for example, our observations are<br />
related to two different categories, ‘schools’ and ‘community centres’.<br />
At a more sophisticated level of classification, we can differentiate more explicitly<br />
between observations. Typically, we can do this where we can identify some<br />
characteristics which observations have in common, the better to understand what<br />
distinguishes them. We may want to distinguish clearly between ‘apples’ and ‘pears’,<br />
for example, as different varieties of fruit. Here the concept ‘fruit’ becomes a<br />
variable, whose values are ‘apples’ and ‘pears’. A variable is just a concept which
