Applying V to study achievement gaps

In the last post I talked about one method to estimate distributional differences from ordinal data, such as those reported by statewide accountability systems. In this post, we’ll put this method to work for the state of California. I’ll show how we can estimate school-level Hispanic/White achievement gaps for every school in the state that reports data on both groups. In California, this means the school must have at least 30 students in each group, for the corresponding grade.

Estimating important things with public data

Intro One of the neatest things I’ve learned about in the last few years is how to estimate effect sizes from coarsened data. The original article discussed using the method with publicly available data reported by statewide education agencies, and that’s the approach I’ll use here too. But more generally, the method could be applied in any situation in which a continuous distribution is reported out in ordinal bins.

Looking into #KeepFamiliesTogether

This week I’m at the Seattle branch of the Summer Institute on Computational Social Science. Today, we discussed digital trace data and spent some time thinking about different sources of digital trace data. One of the easiest sources is twitter, and thanks to Mike Kearney, it’s easily accessible in R via the {rtweet} package! I joined a group addressing a topic I find myself dwelling on throughout the day - the immigration crisis at the border.
