Document Summary
The truth, the media and the popular imagination. Numbers are helpful but also look at qualitative data and not just states. Do(cid:374)"t do o(cid:374)e or a(cid:374)other do both. Theory and policy require statistics about the decisions of those who break the law; about the decisions of those who maintain it; and about what people think of all this. Validity: the extent to which a tool or instrument actually measures the concept a researcher claims to be interested in. Good measure for what there are measuring. Crime rate = amount of crime / population size x 100,000 = standard rate by 100,000. R: if the t(cid:449)o (cid:272)ities did(cid:374)"t (cid:373)easure their (cid:272)ri(cid:373)e rates the(cid:374) its poor relia(cid:271)ility. V: define the variables of intrest in the same way. Administrative records can be compiled to form statistics: you must first decide upon your data ele(cid:373)e(cid:374)ts: your le(cid:448)el of aggregatio(cid:374); a(cid:374)d you"re (cid:272)ou(cid:374)ti(cid:374)g pro(cid:272)edures. Define what your studying: what you are counting; assault, rape, knife.
