主题：[求助]统计有误？

两个表的类别，根本就不匹配。

请做一个可以正常统计的例子发上来。

代码没错，绝对是你手工计算有问题。

StatusBar.Message1= "正在统计"
StatusBar.ProgressBar.Visible =True
StatusBar.ProgressBar.Minimum = 0
StatusBar.ProgressBar.Maximum =DataTables("答案2").datarows.count
Dim dtb As New DataTableBuilder("督学测评统计表")
dtb.AddDef("单位",Gettype(String),8)
dtb.AddDef("单位代码",Gettype(String),8)
dtb.AddDef("教职工数",Gettype(Double))
dtb.AddDef("类别",Gettype(String),8)
dtb.AddDef("调查人数",Gettype(Double))
dtb.AddDef("得分",Gettype(Decimal))
Dim djs() As String = {"是或好","否或不好"}
For i As Integer = 1 To 7
    For Each dj As String In djs
        dtb.AddDef("内容"& i & dj & "人",Gettype(Decimal),"","内容" & i & "_"& dj &"_人数")
        dtb.AddDef("内容"& i & dj & "%",Gettype(Decimal),"","内容" & i & "_"& dj &"_%")
    Next
Next

1、你手工计算的肯定有错；

2、相加以后在平均误差会小一点，不然每次计算都丢失精度
