Standard deviation in statistics, typically denoted by σ, is a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values in a set of data. The lower the standard deviation, the closer the data points tend to be to the mean (or expected value), μ. Conversely, a higher standard deviation ...

Flag STATISTICS_NORECOMPUTE just disable any future automatic statistic updates. In case you have special automated procedure to update statistics that option is needed. However, most of the time statistics auto-update works fine and better to skip STATISTICS_NORECOMPUTE option to prevent query optimizer from picking …The correlation coefficient is a measure of how well a line can describe the relationship between X and Y. R is always going to be greater than or equal to negative one and less than or equal to one. If R is positive one, it means that an upwards sloping line can completely describe the relationship. One of the first steps in computing descriptive statistics is to ensure that your data is properly sorted and organized in Excel.
