No significant correlations between the performance scores and population density were found. Although no relationship was found, performance measures are likely impacted more by the density and veracity of spotter networks than by the amount of residents. There seems to be a slight correlation with radar distance and two performance measures: False Alarm Ratio and Critical Success Index. Furthermore, a collection of counties with similar population densities at varying distances were grouped together for comparison purposes with the performance measures. Results of this collection showed a more pronounced relationship for all measures. There is also a moderate correlation between the normalized number of warnings and events with both population density and distance to the nearest radar.
