Easily interpreted: The result of the calculation is a single number, with a higher score usually means higher risk. Furthermore, many scoring methods enforce some form of monotonicity along the measured risk factors to allow a straightforward interpretation of the score (e.g. risk of mortality only increases with age, risk of payment default ...
Statistical risk is a quantification of a situation's risk using statistical methods.These methods can be used to estimate a probability distribution for the outcome of a specific variable, or at least one or more key parameters of that distribution, and from that estimated distribution a risk function can be used to obtain a single non-negative number representing a particular conception of ...

RR < 1 means that the risk of the outcome is decreased by the exposure, which is a "protective factor" RR > 1 means that the risk of the outcome is increased by the exposure, which is a "risk factor" As always, correlation does not mean causation; the causation could be reversed, or they could both be caused by a common confounding variable ...
Crime statistics refer to systematic, quantitative results about crime, as opposed to crime news or anecdotes. Notably, crime statistics can be the result of two rather different processes: Notably, crime statistics can be the result of two rather different processes:

Empirical tests also provide insight into the quality of the questionnaire. This can be done by: conducting cognitive interviewing. By asking a sample of potential-respondents about their ...
