This interval is called the confidence interval, and the radius (half the interval) is called the

**margin of error**, corresponding to a 95% confidence level. Generally, at a confidence level , a sample sized of a population having expected standard deviation has a**margin of error**This is a big difference from getting a positive

**percent****error**, which means the experimental value is a velocity that is greater than the speed of light (violating the theory of relativity) and is a newsworthy result.**Formula**. The RMSD of an estimator ^ with respect to an estimated parameter is defined as the square root of the mean square**error**: (^) = (^) = ((^)). For an unbiased estimator, the RMSD is the square root of the variance, known as the standard deviation.In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, often that variable's mean.The sign of the deviation reports the direction of that difference (the deviation is positive when the observed value exceeds the reference value).

The 2012 FIA

**Formula One World Championship**was the 66th season of FIA**Formula**One motor racing. It featured the 63rd FIA**Formula One World Championship**, a motor racing series for**Formula**One cars, recognised by the Fédération Internationale de l'Automobile (FIA) – the governing body of motorsport – as the highest class of competition for open-wheel racing cars.For example, using the stream of payments {−4000, 1200, 1410, 1875, 1050} and initial guesses = and = the secant

**formula**with correction gives an IRR estimate of 14.2% (0.7%**error**) as compared to IRR = 13.2% (7%**error**) from the secant method.Specific

**humidity**. Specific**humidity**(or moisture content) is the ratio of the mass of water vapor to the total mass of the air parcel. Specific**humidity**is approximately equal to the mixing ratio, which is defined as the ratio of the mass of water vapor in an air parcel to the mass of dry air for the same parcel.**Caldor**, Inc. was a discount department store chain founded in 1951 by husband and wife Carl and Dorothy Bennett. Referred to by many as the Bloomingdale's of discounting,**Caldor**grew from a second story "Walk-Up-&-Save" operation in Port Chester, New York into a regional retailing giant.
