- Simple Stats - Complete set of Observational statistics for a set of data
- Linear Regression - Least-squares trend line for a set of data

- One Way ANOVA - One way Analysis of Variance for three sets of data

`"Expected Result" = ("Column Total" * "Row Total")/"Sample Size"`

`χ2 = sum( (O-E)^2/E) =sum(O^2/E) - sum(O)`

`"Degrees of Freedom" = (R-1)*(C-1)` if R≠1, then DF = C-1
