We need an algorithm that can handle the following use case. Let's suppose I have a set {​n1.......ni}​ and I compute the percentile rank. I want an algorithm that allows me to replace one or more values in the set (i.e. remove set member n5 and replace it with n9. Rather than re-compute the percentile rank across the whole set, I do the following: 1. compare the value the value replaced with the new value 2. based on some difference between the values adjust the percentile rank This can be defined in a statistical formula

This is data in SPSS format. There is about 200 variables. This is a SPSS .sav data file. We need to find if one of the colleges (AG, coded as 4) will significantly impact retention (retainedfall2010, 1=retained, 0=not retained). Thus far I have: However, students from AG have lower retention rate than other faculties with only 71.4%. Assessing Chi-square test for independence (χ^2=6.035, significance = 0.536), retention rate is independent from college type at 95% confidence level. So question is: Can you tell if AG has significant affect on retention? What test to use? What are the values? How do you interpret the values? Thanks!
