Scatter Diagrams and SPC for Excel

Our SPC software, SPC for Excel, easily creates scatter diagrams.   A scatter diagram gives a visual picture of the relationship between two variables.  One variable is plotted on the x axis and one on the y axis.  The paired results can show a positive correlation, a negative correlation or no correlation.   The p value for the best fit line helps determine if the correlation is significant.
