Methodology: Rhode Island’s Top High Schools 2013
Tuesday, May 07, 2013
GoLocal uses data from the Rhode Island Department of Education's public databases; the analysis reflects the most current data on this site as of April, 2013.
Process and weighting formulas
What followed was precise statistical analysis, guided by a methodology used in similar rankings created elsewhere in New England. After collecting the relevant data, we calculated the average values in each of the categories and the degree to which each school either exceeded or failed to reach those averages.
Those deviations from the average were standardized so that different categories could be compared meaningfully, and then we used a weighting formula to give certain categories more importance than others. We wanted, for example, a school’s student-teacher ratio to matter more in our ranking than its Math SAT scores – though test scores all together account for 60% of the weighting.
The weightings for calculations were as follows:
Student/Teacher Ratio 15%
Per Pupil Spending 15%
Graduation Rate 10%
Each school’s weighted numbers were added into a single evaluative number, which, when ordered from highest to lowest, yields the ranking.
