The selected Statistics calculations are applied to the entire DataStack.
Statistic | Description |
Correlation Coefficient | Linear Correlation Coefficient measures the strength and the direction of a linear relationship between two variables. |
Count | |
Cp | Capability index (potential capability) |
Cpk | Capability index (potential capability corrected for centering) |
CpM | Capability of process index influenced by the difference between the sample mean and the nominal target value. |
CR | Capability Ratio |
Hi | The highest value in the specified DataSet row. |
Kurtosis | Measure of flatness of a distribution |
Lo | The lowest value in the specified DataSet row. |
Mean | The mean value of the valid data within a DataSet. The mean is the sum of values divided by the number (sample size) of values (i.e., the average value of a set of numbers). |
Multiply As Percentages | A type of Six Sigma calculation performed on the selected DataStack(s). |
Pp | Performance index. |
Ppk | Performance index. |
PR | Performance ratio. |

Subgroup Count | |
Subgroup Hi | |
Subgroup Invalid Count | |
Subgroup Lo | |
Subgroup Mean (XBar) | |
Subgroup Moving Average | |
Subgroup Moving Range | |
Subgroup Range | |
Subgroup Standard Deviation | Standard deviation of a subgroup within a sample of data. Used to calculate Sbar. |
Subgroup Sum | |
Subgroup Valid Count | |
Sum | The sum of all valid data within a DataSet row. |
Variance | Returns the Variance value of a DataSet row. In a population of samples, the Variance value is the mean of the squares of the difference between the respective samples and their mean. Basically, it is the measure of the spread of data, or the standard deviation, squared. |
Worst |
