Quizplus · Accepted Answer

The index that measures the strength of the relationship between the independent and dependent variables is ETA, also known as eta-squared (eta²). This index represents the proportion of variance in the dependent variable that is explained by the independent variable. Therefore, C is the best choice among the given options. The other options, i.e., standard error of difference, power, and alpha, do not provide information about the strength of the relationship between the independent and dependent variables.
