Answer :
The X2 statistic is used to determine association between categorical variables, and it cannot be negative. The value -0.35 cannot be a valid value
The chi-square (X2) statistic is used to determine whether there is a significant association between two categorical variables. The X2 score is calculated based on observed and expected frequencies.
Since the X2 statistic is always positive and measures the degree of association, it cannot take negative values. Therefore, the value -0.35 cannot be a valid value for a research X2 score.
On the other hand, 0, 0.35, and 35.5 could be valid values for a research X2 score, depending on the specific research context and sample size.
