Statistical significance. In statistical hypothesis testing, [1] [2] a result has statistical significance when a result at least as "extreme" would be very infrequent if the null hypothesis were true. [3] More precisely, a study's defined significance level, denoted by , is the probability of the study rejecting the null hypothesis, given that ...
However, when looked at in relative terms, wealth is highly concentrated: the bottom 50% of Americans only share 2% of total household wealth while the top 1% hold 35% of that wealth. In the United States, as of 2019, the median household income is $60,030 per year and the median household net worth is $97,300, while the mean household income ...
Age-standardized death rate from cancer per 10,000 people. [210] Estimates are that in 2018, 18.1 million new cases of cancer and 9.6 million deaths occur globally.[211] About 20% of males and 17% of females will get cancer at some point in time while 13% of males and 9% of females will die from it.
In general, an n-log reduction means that the concentration of remaining contaminants is only 10 −n times that of the original. So for example, a 0-log reduction is no reduction at all, while a 1-log reduction corresponds to a reduction of 90 percent from the original concentration, and a 2-log reduction corresponds to a reduction of 99 ...
Thus, a true 50–40–90 season requires a player to achieve or exceed 50.0 percent field goal efficiency, 40.0 percent three-point field goal efficiency and 90.0 percent free-throw shooting efficiency. The NBA requires a player to make at least 300 field goals, 82 three-pointers, and 125 free throws to be a leader in the respective category.
The expression " 1000 percent " or " 1000% " in a literal sense means one thousand in every hundred, and is used as a deliberate hyperbolism for effect. In American English it is used as a metaphor meaning very high emphasis, or enthusiastic support. [1] It was used in the 1972 U.S. presidential election by presidential candidate George ...

[1] Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences.
Mean time between failures ( MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system during normal system operation. MTBF can be calculated as the arithmetic mean (average) time between failures of a system. The term is used for repairable systems while mean time to failure ( MTTF) denotes the expected ...
