St. Cloud State University Benchmark Comparisons August 2007
... Precision-weighted means (produced by Hierarchical Linear Modeling) were used to determine the top 50% and top 10% institutions for each benchmark, separately for first-year and senior students. Using this method, benchmark scores of institutions with relatively large standard errors are adjusted su ...

... experiment to be valid. There could be systematic differences between students who volunteer at the beginning of the semester and those who volunteer at the end. This could lead one to mistake the treatment effect for this difference. Therefore, random assignment is more important than random sampli ...

The mean, median and mode are three different ways of describing the average. • To find the mean, add up all the numbers and divide by the number of numbers. • To ...
