Minimum detectable effect size for main outcomes (accounting for sample
design and clustering)
Assuming average intention to repatriate (proxy for bad attitudes towards immigration) is 0.28 (sd 0.45) - we calculated these data from Florio (2022), who collects data from a similar sample of students from Rome -, power of 0.8, a Type-I error of 0.05, we are able to detect a minimum effect of 0.13 or better.
