在一项元记忆发展研究中,研究者从初一、初二、初三三个年级中各随机抽取8名学生参加实验。实验的任务是:学习5大类共50个单词,每一大类都有10个单词。单词打印再一张纸上,顺序是随机。学会后进行自由回忆,然后按照某种规则计算其输出的群集分数,结果如下表:or-|||-∠-|||-可见:14克里的14-|||-x1 ×2 ×3 ×5 xī ×9 x10 test fiter s 只里 兄里 兄里-|||---- 58.5 50.0 45.B| .6 0 2-|||-65 18.0 110.6 61.2 55.0 48.0 B .8 6 0 2-|||-2 2 60 15.3 103.2-|||-, 70 1125 65 0 0 2-|||-4 4 73 19.1 109.7 .0 56.0 51.5 1.5 1.5 1 2-|||-11 183 106.8 59 6 so o 490 12 12 12-|||-5-|||-分 6 61 19.5 111.1 63.1 55.5 50.5 .6 0 2-|||-1017 106 11 ng li 61 0 470-|||--------- 8 e 17.4 109.5 80 9 53.0 48.5 s 0 2-|||-9 9 63 17.8 109.2 61.3 53.0| 49.5 12-|||-10 10 2| 69 15.9 107.0 60.3 51.0 T7.0 .6 .5 12-|||-.44······ 11 156 10d his is 40 10 10-|||-12 12-|||-13 13 17.3 105.5 59.7 55.0 52.0| .6 12-|||-14 14 16.1 108.7 60.6 62.0| 48.0 1.2| 1 2-|||-15 1h2 1017 h/3 20 " 02-|||-.-16 -- 18 to 15.3 108 2 61.1 50.5 47.5 6 12-|||-15.1 100.1 ,-|||-55.2 52.0 48.0 1.0 0 2-|||-17 17 64 19.9 110.2 63.0 94.0-|||-48 18 69 19.5 108.2 62.9 49.8 .6 12-|||-65.B 51.0 0 2-|||-19-|||-20一 20 17.5 106.9 60.9 54.0 49.4 1.0 1.0 0 2-|||-21 18.9 1122 62.5 54.2 49.5 1.0 0 2-|||-22 17.7 109.0 62.1 62.0| 49.0 2 1.5 02-|||--23-··· 23 63| 170 64 0 49 5 10 B 02-|||-17 3 1103 62 8 60 5 10-|||-24 24 64 19.2 105.2 60.5 49.5 49.5 1.2 6 12-|||-26- 25 60 15.2 105.0 0 2-|||-58.8 50.0 50.0| 1.2 12-|||-26 26 2| 61 16.4 07.5 61.5 62.0 49.0 1.0 .0 6| 12-|||-27 17 2 106 8 620 62 5 12 12 02-|||-一-|||-应量训图-|||-e a W 45这些学生在记忆过程中的策略水平有无年级差异其发展是均衡的吗描述分数N均值标准差标准误均值的 95% 置信区间极小值极大值下限上限初一820.87506.468332.2869015.467326.282710.0030.00初二822.37507.539182.6655016.072128.677912.0035.00初三829.87505.194431.8365125.532334.217724.0040.00总数2424.37507.376891.5058021.260027.490010.0040.00方差齐性检验分数Levene 统计量df1df2显著性.644221.535ANOVA分数平方和df均方F显著性组间372.0002186.0004.441.025组内879.6252141.887总数1251.62523
