Statistical tests are used to determine how likely it is that data or experimental results are due to chance rather than a real difference. One of these statistical tests is called the Chi-Square (chi^2) Test of Goodness of Fit. With the Chi-square Test, you can determine the probability that the observed results match what you expected or determine the probability that they are significantly different from what you expected. Let’s do an example using the Chi-Square Test. If you were to toss a coin 100 times, How many heads would you expect in theory? _____ How many tails would you expect in theory? _____ Therefore, what would your hypothesis be for the results of 100 coin tosses?
