At Westmont High School (WHS)—a Title 1 school just outside Chicago, IL—our team has sustained tremendous growth and significant gains in student achievement. WHS continues to rank in the top 1 percent in Illinois and in the nation for its graduation rate. Over the past five years, 98.5 percent of our students have graduated on time, up from a 10-year average of 90 percent. For five years straight, 100 percent of Latino and African-American students at WHS have completed all graduation requirements on time. In addition, WHS can also claim one of the most improved and top performing AP programs in Illinois and in the nation.

It is not, however, a static process. In order to maximize its effectiveness constant reevaluation is required. Otherwise conclusions made based on statistics can quickly become inaccurate and irrelevant.
One powerful example of such numerical evolution was evident in the aftermath of the gubernatorial election in Virginia. When the final results had been tabulated several newscasts explained the victory in these terms—the Democrat won the women’s vote by a larger margin than the Republican won the men’s. From there the speculation became focused on what specific issues had caused this “gender gap”.
But a day later another set of numbers presented a significantly different perspective. When one statistician divided the same voters into the category of either “married” or “unmarried” new conclusions emerged. A majority of married men and married women favored the GOP; unmarried men and women did not. Suddenly, because of these numbers the conversation and potential suppositions veered in a very different direction.
Similar numerical adjustments are occurring in the world of sports. A recent article in the Washington Post explained that the Nationals new baseball manager Matt Williams based a large portion of his improvement plan on the introduction of something new to the organization—data analysis. The plan is basic. An individual will be hired who will filter through the statistics provided (more…)
