From: Identifying low test-taking effort during low-stakes tests with the new Test-taking Effort Short Scale (TESS) – development and psychometrics

   TESS values
External criterion Group M (SD) N ANOVA
BPT test time Fast performersa 2.29 (1.06) 257 F(1) = 258.70; p < 0.001; η2 = 0.35
Slow performersb 3.70 (0.87) 237

High performersd 3.50 (1.08) 110
