1、Excel学生成绩、各种报表统计常用公式1、分数段人数统计90-100分：=COUNTIF(C4:C18,">=90")80-89分：=COUNTIF(C4:C18,">=80")-COUNTIF(C4:C18,">=90")70-79分：=COUNTIF(C4:C18,">=70")-COUNTIF(C4:C18,">=80")60-69分：=COUNTIF(C4:C18,">=60")-COUNTIF(C4:C18,">=70")50-59分：=COUNTIF(C4:C18,">=50")-COUNTIF(C4:C18
2、,">=60")41-49分：=COUNTIF(C4:C18,">40")-COUNTIF(C4:C18,">=50")40分及以下：=COUNTIF(C4:C18,"<=40")2、最高分：=MAX(C4:C18,G4:G18,K4:K18,O4:O13)最低分：=MIN(C4:C18,G4:G18,K4:K18,O4:O13)总分：=SUM(C4:C18,G4:G18,K4:K18,O4:O13)平均分：=AVERAGE(B4:D4)3、与考人数、记分人数：=COUNT(C4:C18,G4:G18,K4:K18,O4:
3、O18)优生人数：=COUNTIF(C4:C18,">=80")差生人数：=COUNTIF(C4:C18,"<=40")双科合格人数：=SUMPRODUCT((C4:C18>=60)*(D4:D18>=60))双科优秀人数：=SUMPRODUCT((C4:C18>=80)*(D4:D18>=80))4、条件求和：=SUMIF(B2:B56,"男"，K2:K56)——假设B列存放学生的性别，K列存放学生的分数，则此函数返回的结果表示求该班男生的成绩之和；5、学生分数转化为等级评定：=IF(A4>=80,"优",IF(A4>=
4、70,"良",IF(A4>=60,"合格","待合格")))1、2、3、4要与优、良、合格、待合格相对应=CHOOSE(IF(A1>=80,1,IF(A1>=70,2,IF(A1>=60,3,4))),"优","良","合格","待合格")这两个函数指不录入成绩时，单元格为空。录入0时，评定为待合=IF(C4>=80,"优",IF(C4>=70,"良",IF(C4>=60,"合格",IF(ISNUMBER(C4),"待合",IF(ISBLANK(C4),"")))))=LOOKUP(A1,{0,60,70,80},{"D"
5、,"C","B","A"})=LOOKUP(A1,{0,60,70,80,90},{"不及格","及格","中","良","优"})=IF(E4<60,"D",IF(E4<70,"C",IF(E4<80,"B","A")))=if(A1<60,"E",if(A1<70,"D",if(A1<80,"C",if(A1<90,"B","A"))))=IF(A1<60,"不及格",IF(A1<70,"及格",IF(A1<80,"中",IF(A1<90,"良","优"))))=IF(A1>=90,"优",IF(A1<90,"良","
6、if(a1<70,"中",if(a1=<60,"及格","很差")))=IF(AND(C5>=90,C5<=100),"A",IF(AND(C5>=80,C5<90),"B",IF(AND(C5>=70,C5<80),"C",IF(C5<70,"D",E)))).多科目等级评定：=CONCATENATE(IF(C2>=80,"A",IF(C2>=60,"B","C")),IF(D2>=80,"A",IF(D2>=60,"B","C")),IF(E2>=80,"A",IF(E2>=60,"B","C")))=IF(C2>=8
7、0,"A",IF(C2>=60,"B","C"))&IF(D2>=80,"A",IF(D2>=60,"B","C"))&IF(E2>=80,"A",IF(E2>=60,"B","C"))6、18位身份证号码转换成出生日期的函数公式：如果E2中是身份证,在F2中求出出生日期，=DATE(MIDB(E2,7,4),MIDB(E2,11,2),MIDB(E2,13,2))格式为yyyy-m-d，可更改为yyyy-mm-dd的格式。补充说明：注意检查括号是否成对出现其余的为18位的身证，就从第9位开始提取8位是15位的，就从第7位
8、开始，提取6位（1）=IF(LEN(A1)=15，MID（A1，7，6），MID（A1，7，8）)注意检查括号是否成对出现判断是几位的身份证提取后格式为670520或19670520。将多个文本字符窜成一个（2）如果身份证都是18位的，也可能直接用=MID（A1，7，8）（3）提取后的出生日期是连续的，
