All the calc are much the same. On my Casio fx825x
Select statistic mode. "Mode" "."
enter each sample value followed by "M+" which should be marked as "data"
in a different color
After N numbers are input, read out the statistics eg
shift "7" gives mean
shift "8" gives standard deviation

which keys should be marked in a different color
