P value and statistical significance:

The P value answer this question: If the theory that generated the expected values were correct, what is the probability of observing such a large discrepancy (or larger) between observed and expected value? A small P value is evidence that the data are not sample from the distribution you expected. The chi.square calculations are ony reliable when all the expected values are 5 or higher. This assumption is violated by your data, so the P value may not be very accurate.
