Variable and attribute (research)

<h2 id="examples">Examples</h2>
<p><a href="/facts/Ageing/AxL4qCW4">Age</a> is an attribute that can be operationalized in many ways. It can be dichotomized so that only two values – "old" and "young" – are allowed for further data processing. In this case the attribute "age" is operationalized as a binary variable. If more than two values are possible and they can be ordered, the attribute is represented by ordinal variable, such as "young", "middle age", and "old". Next it can be made of rational values, such as 1, 2, 3.... 99.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a>
</p><p>The "social class" attribute can be operationalized in similar ways as age, including "lower", "middle" and "upper class" and each class could be differentiated between upper and lower, transforming thus changing the three attributes into six (see the <a href="/facts/Social_class/gJbHDVNc">model proposed by William Lloyd Warner</a>) or it could use different terminology (such as the <a href="/facts/Working_class/vX7fPNBo">working class</a> as in the <a href="/facts/Social_class/gJbHDVNc">model by Gilbert and Kahl</a>).
