You can put this solution on YOUR website!
mean is adding and dividing by the number
sd is taking there difference from each value and the mean, squaring it, adding all the squared values, and dividing (here) by 19.
mean is 20.85
std dev is 5.94
Can enter into STAT EDIT the values, then STAT CALC 1varstats ENTER.
