I dont know how to put my data in spss

#1
I have a problem.

I have counted the angle in which bacteria lie. 1-10, 11-20, 21-30 till 180.
1 have 3 diffrent treated cultures. A, B, C
Every culture i have taken 3 pictures and counted the angle of some bacteria.
How do i know if the difference in angle division is significant.
And if my populations are normally divided?

How do i put in my data?
