Chi Square Test for Gaussian Distribution

[miztaken]

Hi there,
I have very naive to statistics.

I have a set of data points. that can be like

10, 12, 13, 14 ,15 , 15, 12, 13 17, 18, 19, 12, 19, 20 ....

Now i need to know if these days points follows any gaussian distribution / normal distribution or not?

IS chi -square test the right way to test this?

If yes, what steps do i have to take to accomplish this.. also it will be good if there is any free tool that can help me do this?

if no, what do i have to do...to know the distribution my datapoints follow?/

Thank you very much for your time..

To test for normality, a http://en.wikipedia.org/wiki/Normal_probability_plot" would be more appropriate.
