Learning Objectives

  1. Define "descriptive statistics"
  2. Distinguish between descriptive statistics and inferential statistics

Some descriptive statistics are shown in Table 1. The table shows the average salaries for various occupations in the United States in 1999. (Click here to see how much individuals with other occupations earn.)

NOTE: Unmarried includes never-married, widowed, and divorced persons, 15 years or older.

These descriptive statistics may make us ponder why the numbers are so disparate in these cities. One potential explanation, for instance, as to why there are more women in Florida than men may involve the fact that elderly individuals tend to move down to the Sarasota region and that women tend to out live men. Thus, more women might live in Sarasota then men. However, in the absence of proper data, this is only speculation.
