In other words, if you have an accurate count of how many 2-heads, and 2-tails tosses were observed, then you already know how many of the tosses ended up as mixed head-tails, so the third measurement provides no additional information. Interpreting the Chi Square Value With the Chi-square calculation table completed, you would look up your Chi-square value on the Chi-square Distribution table at the back of this activity.

The columns in the Chi-square Distribution table with the decimals from .995 through .005 refer to probability levels of the Chi-square. For instance, 3 events were observed in our coin toss exercise, so we already calculated we w...
