Math 7 Students: Theoretical versus Experimental Probability?

Math 7 and accelerated students were given clues about how a spinner was colored in based on percentages and fractions. They came up with the theoretical probability. Then we gathered data from 5 of the groups of students who spun their spinner 10 times using a pencil and a bent paperclip. Here are the results.

What does this tell you? What is the difference between experimental and theoretical probability? What would change if we got data from all 8 groups instead of just 5 groups?
