Maths Algorithms in C#: The Arithmetic Mean
The arithmetic mean is defined as the average of a set of data. It is found by taking the sum of each value in the data set, and then dividing by the total number of data points.
public static double ArithmeticMean(List<double> values)
{
double mean, sum;
sum = 0.0;
foreach (double value in values)
{
sum += value;
}
mean = sum / (double)values.Count;
return mean;
