So weighting by country year is also likely to produce problems with your data.
The criteria and weighting remain the same for this year, but the results vary.
These airports were ranked in seven categories, with weighting as noted below.
Like Silver, I question the seemingly arbitrary cutoffs and weighting of the data Wang uses in his model.
That critical number—the biggest pool of youngish, single men—encompassed 60% of the weighting.
It was better to lose a part than run the risk of discovery by weighting himself too much.
The weighting agents most generally used are sugar and acetate of lead.
This is done either by leading the cable through another anchor or by weighting the cable with ballast.
It is supposed to have been used for weighting a fishing net.
The weighting process kept even pace with the other ghastly details.
Old English gewiht, from Proto-Germanic *(ga)wekhtiz, *(ga)wekhtjan (cf. Old Norse vætt, Old Frisian wicht, Middle Dutch gewicht, German Gewicht), from *weg- (see weigh). The verb meaning "to load with weight" is attested from 1747; sense in statistics is recorded from 1901. To lose weight "get thinner" is recorded from 1961. Weight Watcher as a trademark name dates from 1960. To pull one's weight (1921) is from rowing.
The force with which a body is attracted to Earth or another celestial body and which is equal to the product of the object's mass and the acceleration of gravity.
A measure of the heaviness of an object.
Our Living Language : Although most hand-held calculators can translate pounds into kilograms, an absolute conversion factor between these two units is not technically sound. A pound is a unit of force, and a kilogram is a unit of mass. When the unit pound is used to indicate the force that a gravitational field exerts on a mass, the pound is a unit of weight. Mistaking weight for mass is tantamount to confusing the electric charges on two objects with the forces of attraction (or repulsion) between them. Like charge, the mass of an object is an intrinsic property of that object: electrons have a unique mass, protons have a unique mass, and some particles, such as photons, have no mass. Weight, on the other hand, is a force due to the gravitational attraction between two bodies. For example, one's weight on the Moon is 1/6 of one's weight on Earth. Nevertheless, one's mass on the Moon is identical to one's mass on Earth. The reason that hand-held calculators can translate between units of weight and units of mass is that the majority of us use calculators on the planet Earth at sea level, where the conversion factor is constant for all practical purposes.
