find the center point of coordinate 2d array c#

Question

Is there a formula to average all the x, y coordinates and find the location in the dead center of them.

I have 100x100 squares and inside them are large clumps of 1x1 red and black points, I want to determine out of the red points which one is in the middle.

I looked into line of best fit formulas but I am not sure if this is what I need.

Sometimes all the red will be on one side, or the other side. I want to essentially draw a line then find the center point of that line, or just find the center point of the red squares only. based on the 100x100 grid.

Answer 1

List<Point> dots = new List<Point>();
int totalX = 0, totalY = 0;
foreach (Point p in dots)
{
    totalX += p.X;
    totalY += p.Y;
}
int centerX = totalX / dots.Count;
int centerY = totalY / dots.Count;
