Next, let’s create a table of observed and expected frequencies for each number on the dice: Note: If we believe the dice is fair, this means we expect it to land on each number an equal amount of times – in this case, 10 times each. See more Next, we need to find the critical value in the Chi-Square distribution table that corresponds to α = .05and df = (#categories – 1). In this case, there are 6 categories, so we will use df = 6 – 1 = 5. We can see that the … See more The Chi-Square test statistic, X2, is calculated as: 1. X2 = Σ(O-E)2/ E The following table shows how to calculate this test statistic: In this case, X2 turns out to be 9.8. See more Since our test statistic is less than the critical value, we fail to reject the null hypothesis. This means we do not have sufficient evidence to say that the dice is unfair.
