表中涂绿的数据都是高于年级平均水平的数据其中1、4、6、7这四个班都占到了四项或以上，说明这四个班的整体情况是非常好的2.班级分数段对比分析班级最高分人数[90-100)[80-90)[70-80)[60-70)[50-60)[40-50)[30-40)[20-30)198225/54/98/173/20　　2/22　298215/57/122/143/173/20　1/21　399225/53/810/182/202/22　　　497223/37/109/192/21　1/22　　598222/210/127/19　1/201/21　1/22694216/67/135/182/201/21　　　793202/28/107/171/181/19　1/20　全部9915028/2846/7448/12213/1358/1432/1454/1491/150从表格中可以看出，90-100这个分数段4、5、7班人数较少，需要做尖子生培养的工作；80-90这个分数段1、3班人数较少，说明老师应该加强中流砥柱的培养对于低分，除了3、6班，其他班级都存在个别低分情况，在50分以下，需要老师对这些同学进行有针对性的援助。

3.班级每个小题分析涂红的数据都是低于年级平均水平的，老师们对照考试细目可以看到自己班哪个知识点掌握的好，哪个知识点掌握的不好，争取在进入下个学段前查漏补缺，让孩子们再做一下相关题目班级k1-1k1-2k1-3k1-4k1-5k1-6k1-7k1-8132.7272.7272.8642.86432.1822.72722.8572.8572.8572.8572.5712.8571.5712.71432.8642.3182.72732.86431.52.864432.7272.8642.8642.8642.8642.1823532.5912.5912.7272.72731.6362.864633332.85732.4293732.852.852.852.72.852.13全部2.962.722.82.882.782.941.942.88班级k1-9k1-10z11-16z11-16(11)z11-16(12)z11-16(13)z11-16(14)z11-16(15)11.9090.81818.5453.9093.7273.0913.8182.54521.571218.0483.9053.6193.2863.6192.47632.3182.04518.7273.9093.18233.5453.27341.2271.77319.86443.8183.3183.9093.45552.4551.63618.8183.9093.6363.3643.4553.45561.7141.85720.5243.9053.9053.7623.813.8172.251.219.643.63.53.73.4全部1.921.6219.1533.9333.643.3273.6933.2班级z11-16(16)z17z18z18((1))z18((2))z18((3))z18((4))z1911.4553.77312.4553.5913.2272.4093.2277.09121.1434.33312.7623.193.6192.6193.333731.8184.54512.5453.1363.2732.9553.1826.81841.3644.27313.0913.2273.5912.7733.57.045514.27312.5452.9553.3182.7733.57.36461.3334.42912.3813.0952.8573.0953.3337.14371.44.311.953.53.052.23.27.15全部1.364.27312.543.243.282.6933.3277.087班级z19((1))z19((2))z20z21z22z2313.7733.3183.53.4551.5451.45523.6673.3333.5243.61911.23833.7273.0913.4093.6821.2270.90943.8183.2273.8643.2271.0911.09153.7733.5914.1822.7730.8640.81863.8573.28643.4291.3811.14373.83.353.753.410.95全部3.7733.3133.7473.3671.161.087。
