Document Summary

Because the sample sizes in eco220y for both males and females are much bigger than. Two things can lead to bigger (cid:1872)-statistics: (1) larger differences between males and females and the original study we would expect smaller standard errors and hence bigger (cid:1872)-statistics (other things equal). There study (budgets 2 and 5) so this and the larger sample sizes both work towards bigger (cid:1872)-statistics (in absolute value). (cid:1834)(cid:2868):(cid:3435)(cid:1868)(cid:3040)(cid:3028)(cid:3039)(cid:3032),(cid:3002)&(cid:3023) (cid:1868)(cid:3040)(cid:3028)(cid:3039)(cid:3032),(cid:2870)(cid:2870)(cid:2868)(cid:3439)=0 (cid:1834)(cid:2869):(cid:3435)(cid:1868)(cid:3040)(cid:3028)(cid:3039)(cid:3032),(cid:3002)&(cid:3023) (cid:1868)(cid:3040)(cid:3028)(cid:3039)(cid:3032),(cid:2870)(cid:2870)(cid:2868)(cid:3439) 0. However, for most budgets there is actually a bigger difference between males and females in the original study so the key factor is the sample sizes. Budget 2 between the original a&v study and the eco220y replication study. (c) for budget 2: (d) for budget 3: (cid:1834)(cid:2868):(cid:3435)(cid:2020)(cid:3033)(cid:3032)(cid:3040)(cid:3028)(cid:3039)(cid:3032),(cid:3002)&(cid:3023) (cid:2020)(cid:3033)(cid:3032)(cid:3040)(cid:3028)(cid:3039)(cid:3032),(cid:2870)(cid:2870)(cid:2868)(cid:3439)=0 (cid:1834)(cid:2869):(cid:3435)(cid:2020)(cid:3033)(cid:3032)(cid:3040)(cid:3028)(cid:3039)(cid:3032),(cid:3002)&(cid:3023) (cid:2020)(cid:3033)(cid:3032)(cid:3040)(cid:3028)(cid:3039)(cid:3032),(cid:2870)(cid:2870)(cid:2868)(cid:3439) 0. +2 understands that tables 1 and 2 compare sexes within each study while tables 3 and 4 compare each sex across the studies (tables 1 and 2 compare the average generosity between sexes within each study.
