range is lowest to hightest: 5 to 24, although many would throw out 24 as an outlier (look that word up)
standard deviation, best done on your calculator, but http://www.calculator.net/standard-deviation-calculator.html?numberinputs=9%2C+24%2C+8%2C+9%2C+5%2C+8%2C+9%2C+10%2C+8%2C+10&x=30&y=26

and if you throw out the outlier, look at what happens to mean and std deviation.
