Here's a simple one for real time data:

// Insert rawdata into array with insertion sort
if (datacount==0) datavals[0]=mcdataval;
for (i=datacount-1; i >=0; i--)
{
if (rawdataval < datavals) datavals[i+1]=datavals;
else
{
datavals[i+1]=rawdataval;
break;
}
}
if (++datacount==16)
{
datacount=0;
mcdataval=(datavals[7]+datavals[8])>>1;
}
