Liam wants to investigate the effect of operant conditioning on study habits. He splits a sample of Year 8 students into two groups. Group 1 receives verbal praise and a reward token (positive reinforcement) every time they complete a voluntary online spelling exercise. Group 2 receives no praise or reward tokens. Liam counts the total number of voluntary online spelling exercises completed by each participant over a two-week period.
State a fully operationalised directional (one-tailed) hypothesis for Liam's investigation.
