several ways of calculating this central tendency, but the simplest and most often used is the arithmetic mean , which is routinely called the average. For a set of N measurements of some quantity x , the arithmetic mean, G x , is defined as the sum of all the data divided by N ...
Standard Deviation, also called mean square error, is various data deviation mean value distance mean value, it is after the divided difference sum of squares average root, with sigma expressed.The standard deviation is the variance arithmetic square root.The standard deviation can reflect a data ...
Various data deviation mean value distance (to divided difference) the mean value, after it is the deviation sum of squares average root.With sigma expressed.Therefore, the standard deviation also is one kind of mean value.The standard deviation is the variance arithmetic square root.The standard...
When the standard deviation is divided by the mean we get. 01:16 The range of first 10 prime numbers is . 01:40 If A and B are mutually exclusive events then P(AcapB)=. 01:34 P(AcupB)+P(AcapB)=. 01:57 The set of all possible outcomes is called. 01:52 If P(A capB)=0.3...

Standard Deviation is a statistical concept that illustrates how a specific set of prices is divided or spread around an average value. The concept is that 68% of data values differ from the middle average value by less than one standard deviation, and that 95% of data values differ from th...
as the standard deviation of a set of observations is 0. (1) the sample number was 0 (2), and the sampling error was 0 (3) the average number is 0 (4) or more 16., a set of data is normally distributed, in which less than X+1.96s variables have values. (1) 5% (2) 95%...
aLoad Coefficient (DLC), which is the standard deviation of the measured dynamic loads divided by the mean axle group load, was used to characterize the dynamic loading for each suspension type. 装载系数(DLC),是被测量的动态装载的标准偏差由卑鄙轨小组装载划分了,使用描绘动态装货为每个悬浮类型。[...
