excel电子表格 宏 高手请进，高分追加

Question

有如下结构的一个表格，3个主要字段是：姓名、考试类型、分数，
考试类型有A、B、C、D 四种。各种考生记录混在一起，我想通过一个宏分别求出：
1、参加不同类型考试的考生，平均分各是多少？
2、参加不同类型考试的考生，最高分和最低分各是多少？(最低分是除0分外的最低分)
3、参加不同类型考试的考生，得最高分和最低分的分别有多少人？
4、参加不同类型考试的考生，考试分数的方差是多少？(var函数是方差函数)

也就是说对考ABCD 4个类型的考生，分别计算上面4种数值。至于结果可以输出到另一个电子表格文件里。
本人水平有限，这题有点麻烦，请高手详细指点。成功后另有100分追加

Sub 分类汇总()

'对sheet1的A:C列进行分类统计汇总，结果放在sheet2的A1:E7

Dim s1 As Worksheet: Set s1 = Worksheets("sheet1") '原数据表
Dim s2 As Worksheet: Set s2 = Worksheets("sheet2") '新数据表
Dim r(1 To 5) As Integer: r(5) = s1.[A65536].End(xlUp).Row '原数据表行数，以A列为准

s2.Cells.Delete: s1.Range("A1:C" & r(5)).Copy s2.Range("A1")
s2.Range("A1:C" & r(5)).Sort Key1:=s2.Range("B2"), Order1:=xlAscending, _
Header:=xlGuess, OrderCustom:=1, MatchCase:=False, _
Orientation:=xlSortColumns, SortMethod:=xlPinYin, DataOption1:=xlSortNormal
s2.Range("f1:i1") = Array("A", "B", "C", "D")
s2.Range("e2:e7") = Application.WorksheetFunction.Transpose(Array( _
"平均分", "最高分", "大于0的最低分", "最高分人数", "最低分人数", "分数方差"))

For i = 1 To 4
r(i) = s2.Range("B:B").Find( _
WHAT:=s2.Cells(1, i + 5), LookIn:=xlValues, LookAt:=xlWhole).Row
Next
r(5) = r(5) + 1

Dim rng(1 To 4) As Range '分类区域
For i = 1 To 4
Set rng(i) = s2.Cells(r(i), 3).Resize(r(i + 1) - r(i), 1)
Next

Dim rs(1 To 6, 1 To 4) '结果
For i = 1 To 4
rs(1, i) = Application.WorksheetFunction.Average(rng(i)) '平均分
rs(2, i) = Application.WorksheetFunction.Max(rng(i)) '最高分
j = 1
Do
temp = Application.WorksheetFunction.Small(rng(i), j): j = j + 1
Loop Until (j > rng(i).Rows.Count) Or (temp > 0)
rs(3, i) = temp '最低分
rs(4, i) = Application.WorksheetFunction.CountIf(rng(i), rs(2, i)) '最高分人数
rs(5, i) = Application.WorksheetFunction.CountIf(rng(i), rs(3, i)) '最低分人数
rs(6, i) = Application.WorksheetFunction.Var(rng(i)) '分数方差
Next
s2.Range("F2").Resize(6, 4) = rs
s2.Range("F2:i2", "f7:i7").NumberFormatLocal = "0.00_ "
s2.Range("F3:i6").NumberFormatLocal = "G/通用格式"
s2.Range("a:d").Delete
s2.Cells.EntireColumn.AutoFit
s2.Cells.EntireRow.AutoFit
s2.Cells.HorizontalAlignment = xlCenter
s2.Activate
End Sub
-----------
原数据表 sheet1
新数据表 sheet2

打开原数据表，在表名上点右键，选“查看代码”，打开代码窗口，将上面的代码复制入其中，并根据实际情况，将代码内的表名改为实际表名（有注释）然后，按 F5 键运行程序
