It is algebraically simpler, though in practice less robust, than the average absolute deviation. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same units as the data.

Microsoft stated that publishers will only need to provide permission to the company to allow the repackaging, and they expect the list to grow significantly over time. Unlike the emulation of original Xbox games on the Xbox 360, the Xbox One does not require game modification, since it emulates an exact replica of its predecessor's environment -- both hardware and software operating systems. The downloaded game is a repackaged version of the original that identifies itself as an Xbox One title to the console. At Gamescom, Microsoft revealed it has plans to ensure ``all future Xbox 360 Games with Gold titles will be playable on Xbox One.'' On December 17, 2015 Microsoft made another sixteen Xbox 360 games compatible with Xbox One, including titles such as Halo: Reach, Fable III and Deus Ex: Human Revolution. On January 21, 2016, Microsoft made another ten Xbox 360 games compatible, including The Witcher 2: Assassins of Kings and Counter-Strike: Global Offensive. On May 13, 2016, Microsoft made Xbox 360 titles with multiple discs compatible, starting with Deus Ex: Human Revolution Director's Cut.

It is believed that the first player to use a protective visor Mark Mullaney of the NFL's Minnesota Vikings in 1984, in order to protect a healing eye injury. Top manufacturers of visors are Nike, Oakley, and Under Armour, with Leader being the first to come out with a visor/shield for former Chicago Bears quarterback Jim McMahon (who needed the visor because of a childhood eye injury). While Mullaney and McMahon's visors were tinted, most of the earlier visors were clear or smoked, but they are now offered in a variety of styles ranging from blue, gold, black, rainbow, silver, or amber. High-school and pee-wee leagues prohibit all but clear visors. This rule was enacted so that training staff and coaches can easily view a player's face and eyes in the case of a serious injury, to discern if the player is conscious. The NCAA banned the use of tinted visors for the same reason, and the NFL has followed suit as well. However, players with eye problems may still obtain special permission to wear tinted visors, some notable examples being LaDainian Tomlinson and Chris Canty.
