The chi-square goodness-of-fit test is used to determine whether observed frequencies significantly deviate from expected frequencies. In most instances, the researcher hopes to find a significant result (indicating that the observations deviate from expectations), which would provide some evidence for a treatment effect. • Share an example of a situation in which the researcher might hope for a non-significant result. Be sure to state why they would hope for such a result. (Type Answer & Explain your example)
