Almost no statistic $($performance measure$){?}^7$ computed during a single simulation replication will be independent and identically distributed $($e$.$g$.,$ the waiting time of entity #$4$ maybe dependent on entity #$3$ waiting and processing times$).$ So instead, we use, for example, the average values computed over the day as an observation $($i$.$e$.,$ we will determine the average of the averages$).$

Question $32$: Are daily averages independent and identically distributed? Why?
