The Kodak C360 offers a fairly standard 3x zoom lens, equivalent to a 34-102 mm zoom on a 35mm camera. Performance at ISO 400 is now quite good by comparison, with output at 11x14 looking like yesterday's 8x10s at this size. In addition, the oversized 2. The KD-400Z also features a Movie mode, activated through the Record menu. HP has today made an announcement that they are to reveal a new range of imaging products including four digital cameras and six printers. The Casio S600 features an updated CCD imager with higher resolution of six megapixels, as well as slightly closer macro focusing distance of 15 centimeters, 50% improved battery life in CIPA tests, an LCD display that is said to be twice as bright as in past models, and a new "Revive Shot" mode which aims to restore bright colors to images of prints that have gradually faded over the years. You can also record short sound clips to accompany images, for a maximum of 15 seconds or as long as the memory card has available space.8"-type CCD sensor, coupled to Casio's proprietary EXILIM Engine image processor.

IQ tests give approximately this Gaussian distribution across a large population. This plot is artificially generated and does not represent any experimental data. It does not reflect narrower spread of women's vs men's IQ, nor does it reflect a bias to low scores due to disability or injury.

An Intelligence Quotient or IQ is a score derived from one of several different standardized tests attempting to measure intelligence. The term "IQ," a translation of the German Intelligenz-Quotient, was coined by the German psychologist William Stern in 1912 as a proposed method of scoring early modern children's intelligence tests such as those developed by Alfred Binet and Theodore Simon in the early 20th Century. Although the term "IQ" is still in common use, the scoring of modern IQ tests such as the Wechsler Adult Intelligence Scale is now based on a projection of the subject's measured rank on the Gaussian bell curve with a center value (average IQ) of 100, and a standard deviation of 15 (different tests have various standard deviations; the Stanford-Binet IQ test has a standard deviation of 16).

IQ scores have been shown to correlate with such factors as morbidity and mortality, parental social status, and to a substantial degree, parental IQ: while IQ inheritance has been investigated for nearly a century, controversy remains as to how much is inheritable, and the mechanisms for inheriting are still a matter of some debate.

IQ scores are used in many contexts: as predictors of educational achievement or special needs, by social scientists who study the distribution of IQ scores in populations and the relationships between IQ score and other variables, and as predictors of job performance and income.

The average IQ scores for many populations were rising at an average rate of three points per decade during the 20th century with most of the increase in the lower half of the IQ range: a phenomenon called the Flynn effect. It is disputed whether these changes in scores reflect real changes in intellectual abilities, or merely methodological problems with past or present testing.
