某Excel成绩表如下所示,若在G13单元格中输入(请作答此空),则G13单元格为平均成绩不及格的学生数。假设学生平均成绩分为优秀(平均成绩≥85)、及格(60≤平均成绩<85)和不及格(平均成绩<60)三个等级,那么在H3单元格中输入( ),并垂直向下拖动填充柄至H12,则可以完成其他同学成绩等级的计算。
- A.COUNT(G3:G12,"<60")
- B.=COUNT(G3:G12,"<60")
- C.COUNTIF(G3:G12,"<60")
- D.=COUNTIF(G3:G12,"<60")
正确答案及解析

解析
本题考查Excel基本概念方面的知识。
Excel规定公式以等号(=)开头,选项A和选项C没有"="故不正确。选项B是错误的,因为函数COUNT的格式为:COUNT(参数1,参数2,……),其功能是求各参数中数值型参数和包含数值的单元格个数,所以公式"=COUNT(g3:g12,"<60")"中G3:G12单元格保存了10个数值,而参数"<60"为非数值型参数,故COUNT计算结果等于10,显然不正确。选项D是正确的,因为函数COUNTIF的格式为:COUNTIF(取值范围,条件式),其功能是计算某区域内满足条件的单元格个数,选项D是计算G3:G12单元格区域中小于60分的单元格的个数,结果等于1。
IF函数的格式为IF(条件式,值1,值2),若满足条件,则结果返回值1,否则,返回值2。IF函数可以嵌套使用,最多可嵌套7层。本题在H3单元格输入选项B"=IF(G3>=85,"优秀",IF(G3>=60,"及格","不及格"))"的含义为:如果G3单元格的值>=85,则在H3单元格填写"优秀",否则如果G3>=60,则在H3单元格填写"及格",否则填写"不及格")。
