Onwuegbuzie et al. (1999) examined foreign-language anxiety as a predictor of foreign-language achievement. They performed a multiple-regression analysis and included other predictor variables, including academic achievement, perceived scholastic competence, and perceived self-worth. They found β (Beta) = −0.39 for foreign-language anxiety and 0.29 for academic achievement. Which of the following explains what this means?
a. There were some uncontrolled variables.
b. The p values are not large enough.
c. More variables should have been included in the multiple–regression analysis.
d. The temporal precedence is not established and there may be another variable that accounts for the relationship.
