If the chi-square result is high, what should you do with the null hypothesis?

  1. Reject

  2. Accept

  3. Consider

  4. Revise

The correct answer is: Reject

If the chi-square result is high, it means that there is a significant difference between the observed and expected values. This indicates that the null hypothesis is most likely not true. Therefore, we can reject the null hypothesis and accept the alternative hypothesis. Option B, accepting the null hypothesis, would not be appropriate in this scenario since a high chi-square result suggests that the null hypothesis is not supported by the data. Option C, considering the null hypothesis, would also not be a valid response as the high chi-square result already suggests that the null hypothesis is not true. Option D, revising the null hypothesis, may be a possible response, but the more appropriate action would be to reject it and consider potential alternative hypotheses. Overall, option A is the best response as it accurately aligns with the concept of rejecting the null hypothesis in the case of a high chi-square result.
