Table 13.7 Recoding <strong>data</strong> to express more meaningful values<br />

<strong>data</strong>, rather than as a result of how we have observed and analysed the <strong>data</strong> for our<br />

own purposes.<br />

As well as recoding values, another path to <strong>data</strong> reduction is through reducing the<br />

number of variables. This can also improve the intelligibility as well as the economy<br />

of our <strong>analysis</strong>. For example, we can see from Table 13.6 that most of the values<br />

assigned for ‘suffering’ are exclusive i.e. for most cases, only one value has been<br />

assigned to that case. The table would be more intelligible and meaningful if we could<br />

name these values. However, we can only do so if the values are exclusive. Suppose<br />

we have subcategorized ‘suffering’ into three subcategories, ‘discomfort’, ‘disability’,<br />

and ‘disfigurement’. Because these subcategories are not exclusive (all three occur in<br />

the first letter) we cannot analyse them as separate values of the variable ‘suffering’.<br />

We would have to analyse them as separate variables, as in Table 13.8.<br />

This is hardly the most economical or intelligible way to present the <strong>data</strong>. As<br />

there is only one case where more than one subcategory has been assigned, we could<br />

accommodate this exception by introducing an additional subcategory, such as<br />

‘multiple’. Then we could treat each of the subcategories as values of the<br />

overarching variable ‘suffering’ (Table 13.9).<br />

This is not ideal, for we are assigning values in terms of more than one dimension,<br />

something all the books warn us not to do! We are distinguishing between those<br />

cases where only one aspect of ‘suffering’ is apparent, and those where more than one
