As the discrepancy between the observed and expected frequencies becomes larger,the magnitude of the chi-square statistic ______.
A)decreases
B)does not change
C)increases
D)increases by a factor of the square of the difference

Question

Quizplus · Accepted Answer

The chi-square statistic is calculated by summing up the squared differences between the observed and expected frequencies, divided by the expected frequency. As the discrepancy between the observed and expected frequencies becomes larger, the squared differences become larger, causing the overall chi-square statistic to increase. Therefore, the correct answer is C - increases.
