Differences in Measurement
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:
“I don’t know what immutable differences exist between men and women apart from differences in their genitals; perhaps there are some other unchangeable differences; probably there are a number of irrelevant differences. But it is clear that until social expectations for men and women are equal, until we provide equal respect for both men and women, our answers to this question will simply reflect our prejudices.”
—Naomi Weisstein (b. 1939)
“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)
