CCS of South Bend Disparity Study 2020 pared to the total weighted availability of M/WBEs, measured in dollars paid, on locally -funded contracts. A "large" or "substantively significant" disparity is commonly defined by courts as utilization that is equal to or less than 80 percent of the availability measure. A substantively significant disparity supports the inference that the result may be caused by the disparate impacts of discrimination. 128A statistically significant dis- parity means that an outcome is unlikely to have occurred as the result of random chance alone. The greater the statistical significance, the smaller the probability that it resulted from random chance alone. A more in-depth discussion of statisti- cal significance is provided in Appendix C. Substantive and Statistical Significance t connotes these values are substantively significant. Courts have ruled the disparity ratio less or equal to 80% represent disparities that substantively significant.

As a result, we explored deeper into the data in order to ensure that an 128.
