I did this with a graphing calculator, the TI-84 Plus CE by Texas Instruments, highly recommend. You can find every function you need for stats in a graphing calculator.
To put the data into your calculator:
'stat' --> ' 1 : Edit...' --> put one value on each row
Go back to the main calculator with '2nd' --> 'quit'
Lastly go back to 'stat' and scroll to 'CALC' at the top, then click the first option, '1 : 1-Var Stats'
If you know the symbols it'll tell you a lot, and there are functions for genuinely everything in stats.
