Mean Plus Minus Standard Deviation. The mean and median are 10 29 and 2 respectively for the original data with a standard deviation of 20 22. In numerical format this is 3 x 0 5064 9 34 10 9.

Fourth calculate three sigma which is three standard deviations above the mean. The sign may also represent an inclusive range of values that a reading might have. Where the mean is bigger than the median the distribution is positively skewed.
In experimental sciences the sign commonly indicates the confidence interval or error in a measurement often the standard deviation or standard error.
The graph that follows shows the relationship between the standard deviation and a gaussian distribution. In mathematics it generally indicates a choice of exactly two possible values one of which is obtained through addition and the other through subtraction. So the standard deviation 0 2564 0 5064. Where the mean is bigger than the median the distribution is positively skewed.
