- Notes: Regressions at the question level for %NR in column 1 and for % Correct in columns 2-5. %NR computed as the total non-response rate in column 3 and as the non-response rate of students in the Mixed-treatment only in column 4. All regressions include session fixed effects. Standard errors clustered at session level in parentheses. \(^{*}\) \(p<0.10\), \(^{**}\) \(p<0.05\), \(^{***}\) \(p<0.01\)
