In the next version of KnowledgeKube we have added new statistical functions and formulas to the graphing question type. Using the new functions is really straightforward, simply select the function you want to apply, the data/series to use and KnowledgeKube will take care of the rest.

Examples:-

**Correlation** - The correlation formula shows the strength of the relationship that exists between two random variables.

**Covariance **- The covariance formula measures the degree of dependence that may exist between two random variables.

**Mean **- The mean formula calculates the average, or mean, of data stored in a data series.

**Median **- The median formula calculates the median of the data stored in a data series.

**Variance **- The variance formula calculates the variance within a group of data.

In a future release we will also add a range of financial formulas to the graphing question type, more on that in a later post.
