Question 21-30
There were two widely divergent influences on the early development of statistical
methods. Statistics had a mother who was dedicated to keeping orderly records of
governmental units (state and statistics come from the same Latin root, status) and a
gentlemanly gambling father who relied on mathematics to increase his skill at playing
the odds in games of chance. The influence of the mother on the offspring, statistics, is
represented by counting, measuring, describing, tabulating, ordering. and the taking of
censuses --- all of which led to modern descriptive statistics. From the influence of
the father came modern inferential statistics, which is based squarely on theories of probability.
Descriptive statistics involves tabulating, depicting, and describing collections of data.
