In statistics, a data point is a set of measurements on a single member of a statistical population, or a subset of those measurements for a given individual. In addition, in statistical graphics, a "data point" may be an individual item with a statistical display; such points may relate to either a single member of a population or to a summary statistic calculated for a given subpopulation.

Famous quotes containing the words data and/or point:
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“One point in my public life: I did all I could for the reform of the civil service, for the building up of the South, for a sound currency, etc., etc., but I never forgot my party.... I knew that all good measures would suffer if my Administration was followed by the defeat of my party. Result, a great victory in 1880. Executive and legislature both completely Republican.”
—Rutherford Birchard Hayes (1822–1893)
