Saw a study a few years ago that finds that school music program participation is significantly correlated with parental wealth, which raises all kinds of confounding factors depending on what's actually being measured (e.g. Was the kid 10ms slower because they didn't get a good breakfast? Or mom got home late from her 2nd job and interrupted her family's sleep?)
