Net Applications and W3Counter use unique visitors to measure web usage. This has the effect that users visiting a site ten times will only be counted once by these sources, while they are counted ten times by statistics companies that measure page hits.
Net Applications also uses country-level weighting to correct for bias caused by variation in sampling rates across countries.

Famous quotes containing the words differences and/or measurement:
“Quintilian [educational writer in Rome about A.D. 100] hoped that teachers would be sensitive to individual differences of temperament and ability. . . . Beating, he thought, was usually unnecessary. A teacher who had made the effort to understand his pupil’s individual needs and character could probably dispense with it: “I will content myself with saying that children are helpless and easily victimized, and that therefore no one should be given unlimited power over them.””
—C. John Sommerville (20th century)
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
