较差法能不能用计算器算出来呢？

不能吧应该，至少现在的我不会用计算器算较差法

' 窗体控件说明：
' Text1(0)~Text1(n-1)：测量值输入文本框数组
' Command1：计算按钮
' Command2：导出报告按钮
' Label2：显示计算结果
' CommonDialog1：保存文件对话框

Option Explicit

Private Sub Command1_Click()
    Dim n As Integer, i As Integer
    Dim sumDiffSq As Double, s As Double
    Dim x() As Double
   
    ' 获取测量次数（文本框数组元素个数）
    n = Text1.UBound + 1
    If n < 2 Then
        MsgBox "测量次数至少需要2次", vbCritical
        Exit Sub
    End If
   
    ' 读取输入数据
    ReDim x(0 To n - 1)
    On Error GoTo inputErr
    For i = 0 To n - 1
        x(i) = Val(Text1(i).Text)
    Next
   
    ' 较差法计算标准偏差
    sumDiffSq = 0
    For i = 0 To n - 2
        sumDiffSq = sumDiffSq + (x(i + 1) - x(i)) ^ 2
    Next
    s = Sqr(sumDiffSq / (2 * (n - 1)))
   
    ' 显示结果
    Label2.Caption = "单次测量实验标准偏差：s = " & Format(s, "0.0000") & vbCrLf & _

' 动态添加测量值输入框

    Dim i As Integer, txt As TextBox
    ' 默认生成10个输入框（可根据需要调整数量）
    For i = 1 To 10
        Set txt = Controls.Add("VB.TextBox", "Text1" & i, Me)
        txt.Index = i - 1
        txt.Left = 100
        txt.Top = 100 + (i - 1) * 400
        txt.Width = 2000
        txt.Height = 300
        txt.Visible = True
        ' 添加标签
        Set lbl = Controls.Add("VB.Label", "Label1" & i, Me)
        lbl.Left = 2200
        lbl.Top = 100 + (i - 1) * 400
        lbl.Width = 1000
        lbl.Height = 300
        lbl.Caption = "测量值" & i

    Next
End Sub
用VBA就可以实现了

不能，只能按照公式自己计算，计算器中只有贝塞尔公式的
