不良合格率怎么算（合格率怎么算）

我提供一个公式给你。

可以找出>90的比例（假设数据在B2:B80)：=COUNTIF(B2:B80,">=90")/COUNT(B2:B80)找出>80和<90的比例,=(COUNTIF(B2:B80,">=80")-COUNTIF(B2:B80,">=90"))/COUNT(B2:B80)找出>70和<80的比例,=(COUNTIF(B2:B80,">=70")-COUNTIF(B2:B80,">=80"))/COUNT(B2:B80)找出>60和<80的比例,=(COUNTIF(B2:B80,">=60")-COUNTIF(B2:B80,">=70"))/COUNT(B2:B80)<60, =COUNTIF(B2:B80,"<60")/COUNT(B2:B80)。
