follows somewhat predictable patterns that can be
examined using probability. An example of a
subjective probability is Cops usually do not

numerically code variables, can be one of 4
levels nominal, ordinal, interval, or ratio. It
is important to identify which level a variable
is, as this impacts the kind of analysis we can
do with the data. For example, descriptive
statistics such as means can only be done on
interval or ratio level data. Please list, under
