In medical experiments, those researchers who are responsible for administering the drug and for noting improvements are not told which subjects receive the drug. As such, it is important to understand how each program collects and reports crime data, and the limitations associated with the data.

In chapter 3 of The Practice of Research in Criminology and Criminal Justice there are four areas of focus.

These data collection systems and measures are routinely used to talk about crime trends and the effect of interventions on crime rates and specific crime types, but because of what is known about the errors in them and what is tacitly assumed about the unknown errorsthat they are even greaterresearchers generally seem uncomfortable about using the available data to draw conclusions. . The measurement properties or level of measurement of a measure is also an important consideration as it affects the selection of statistical techniques that can be used to analyze the data and the interpretation of the data. Generally measurement is the most important and difficult phase of criminal justice research. For many research and policy questions, it is important to analyze crime data at a relatively low level of aggregation, such as county or even census tract.
