Linear regression lines of the population, as well as by class standing all show this positive relationship. With the exception of freshmen, the classes performed very similarly to the population. The freshmen showed a closer relationship between High School and College grades. Again the freshman class stands out from the rest having a correlation over twice of the other classes. The correlation for the upper classes is rather low, indicating that variances from the average are high.
Freshmen tend to more closely follow their high school performance than do other classes.
But the exceptions are many, and both success and failure are options for all students. Caveats This study suffers from several potential flaws. Those with low GPAs are far less likely to want to advertise the fact. My name is Paul and I am doing a research project for statistics on how well performance in high school predicts performance in college.
