英语翻译1:for any set of obsercations,the proportion of the values that lie within K standard deviations of the mean is at least 1-1/k^2,where K is any constant greater than 12:Chebyshev’s theorem is concerned with any set of values; that is the distribution of values can have any ...
However, visual assessment of the data suggested a possible relationship between serum ARTN and joint pain for the mild-moderate-high categories. After removing the severe joint pain category and outliers that were more than two standard deviations from the mean, we re-evaluated the relationship ...

The formula for the sum of the squares of deviations from the means is [2]: where: Xi=ithitem in the set X̄= mean of the set (Xi−X̄) = deviation of each item from the mean. Q. Find the Sum of Squares for the following numbers: 3, 5, 7. ...
The LUR model was retrospectively extrapolated to 1990 using annual local trends derived from the CHIMERE model [43]. For each woman, annual mean concentration of NO2, BaP and PCB153 were evaluated at their geocoded residential addresses for each year from 1990 to 2011. The average of these ...
The statistical term “2 drms” refers to a value that falls within two standard deviations (using the root-mean-squared method) of the sampled performance data mean. Therefore, a stated accuracy of twenty-one meters (2 drms) means that the position error has an error of less than twenty-...
