Congruency and Quadrants

Congruency and Quadrants

The measure of congruency compares the results of the two main questions to each other: how important are each of the variables and how well is the school performing on each of the variables. The equation divides the mean of performance by the mean of importance and multiplies by 100 - thus giving a congruency coefficient based on a 100 scale. A number above 100 means that the item or category is of less importance than the perceived performance and a number below 100 means that the item or category is of greater importance than the perceived performance.

It is possible to have a high degree of congruency with low means or high means of performance and importance - congruency is a measure of the interaction between the two things measured. It may be helpful to plot performance and importance on a grid in which importance is on one axis and performance is on the other axis. An item in the upper right quadrant will have both a high mean of importance and a high mean of performance. An item in the lower left quadrant will have both a low mean of importance and a low mean of performance.  

When you plot the figures, we recommend calculating them based on a reset origin of 0,0. To do this, calculate the average of the means and subtract from that value. You will maintain an accurate scatter plot, but you will have centered your plot. You can use this file to help you make the calculations.         

A note on sample in the benchmarks. The sample group used were respondents who took the survey from Spring 2013 - Fall 2014. This group contains 33,341 unique responses from the following stakeholder groups: Parents (15,063), Students (7,957), Faculty (3,200), Trustees (619), Alumni (6,502). There is a high degree of confidence that this sample group is representative of of the independent school community.
