With descriptive and predictive analytics, the data set is the foundation of the client engagement. This is what the report is based on. With the analysis there may be outliers in the data set. These may be due to errors in recording or exemplary performers.
These data points should be removed from the analysis. To include would have the distinct potential to positively or negatively skew the results, depending on the data and measurement. Removing the noise provides a truer measurement within the scope.
