Module Example
Public Sub Main()
Dim scores() =
{ Tuple.Create("Jack", 78.8, 8),
Tuple.Create("Abbey", 92.1, 9),
Tuple.Create("Dave", 88.3, 9),
Tuple.Create("Sam", 91.7, 8),
Tuple.Create("Ed", 71.2, 5),
Tuple.Create("Penelope", 82.9, 8),
Tuple.Create("Linda", 99.0, 9),
Tuple.Create("Judith", 84.3, 9) }
Dim result = ComputeStatistics(scores)
Console.WriteLine("Mean score: {0:N2} (SD={1:N2}) (n={2})",
result.Item2, result.Item3, result.Item1)
End Sub
Private Function ComputeStatistics(scores() As Tuple(Of String, Double, Integer)) _
As Tuple(Of Integer, Double, Double)
Dim n As Integer = 0
Dim sum As Double = 0
' Compute the mean.
For Each score In scores
n+= score.Item3
sum += score.Item2 * score.Item3
Next
Dim mean As Double = sum / n
' Compute the standard deviation.
Dim ss As Double = 0
For Each score In scores
ss = Math.Pow(score.Item2 - mean, 2)
Next
Dim sd As Double = Math.Sqrt(ss/scores.Length)
Return Tuple.Create(scores.Length, mean, sd)
End Function
End Module输出：
Mean score: 87.02 (SD=0.96) (n=8)
