Arthur carried out a field experiment to investigate whether a restorative justice workshop was effective at reducing antisocial behavior among young offenders on probation. He compared one group of young offenders who completed the restorative justice workshop (Condition A) with a group who received standard probation meetings (Condition B).
Arthur recorded the number of antisocial incidents reported for each participant during a three-month follow-up period.
Arthur's results are shown in Table 2.
Calculate the range for Condition B and complete Table 2 with your answer.
