In
statistics, a statistical population is a
set of entities concerning which
statistical inferences are to be drawn, often based on a
random sample taken from the population. For example, if we were interested in generalizations about
crows, then we would describe the set of crows that is of interest. Notice that if we choose a population like all crows, we will be limited to observing crows that exist now or will exist in the future. Probably,
geography will also constitute a limitation in that our resources for studying crows are also limited.
