A similar chi square test for a separate variable has a statistic value of 12.99 for sample 2. What conclusions can you draw from these two statistics? Observed scores for sample 1 are closer to the expected values than sample 2 scores are to the expected values No conclusions can be drawn from these scores. Sample 2 is significant, but sample 1 is not significant .Observed scores for sample 2 are closer to the expected values than sample 1 scores are to the expected value.
