the results. I would be willing to pay for it but it has to be easily usable. I know that excel does it but I find it too complicated

There are a bunch of free softwares here, take your pick. You may have ordinal data; classifications that may be ranked worst to best but are not numerical.

You should really try to understand whatever statistical method you use at least a little or your conclusions about the data could be completely wrong. Typically in a survey you want to determine the relationship between random chance and real preferences.

You may be surprised to learn that the "calculator" program on your Windows computer has some very usable statistics functions. I used it, myself, for that, not too long ago. I was only entering numbers to get the average and standard deviation, but it did the job easily.

To see if it's good enough for your purposes, launch the program (found in the Accessories part of the Start menu, or by typing 'calc' in the Run box -- also in the Start menu). Then click the View menu and set for Scientific. You will see buttons in a column on the left which are for statistical functions.

For straightforward, and pretty simple, instructions on using them, open the Help menu. I copied the following instructions from the Help files:

---------------------------------------------------------------------------

To perform a statistical calculation

Type your first piece of data, and then click Sta to open the Statistics Box.
Click RET to return to Calculator, and then click Dat to save the value.
Type the rest of the data, clicking Dat after each entry.
Click Ave, Sum, or s.

Notes

You can also use your numeric keypad to type numbers and operators by pressing NUM LOCK.
Ave calculates the mean of the values saved in the Statistics Box, Sum calculates the sum of the values, and s calculates the standard deviation.
After you have entered all of your data, you can see the list by clicking Sta.
The Statistics Box tracks the number of values that you have saved at the bottom of the dialog box. You can delete a specific value from the list by clicking CD, or you can delete all of the values by clicking CAD. Clicking Load changes the number in the Calculator display area to the number selected in the Statistics Box.

---------------------------------------------------------------------------

Once you've entered a few numbers it will be second nature. It's much easier to do than to read about.

I hope that helps in your situation.
