Weights

Weights in large scale assessments

In class, I’ve talked about using weights in large scale assessments. I’ve provided a bit of intuition about using weights and why they are important. Here’s some R syntax to go along with the example I discussed. Imagine there are two schools in one school district. You are asked what is the average score on some measure of students in the district. There are only two schools (school A and B) and their size varies (School A = 100, School B = 1,000).
