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 â = -0.39 for foreign language anxiety. What does this mean?
People with lower levels of anxiety about learning a foreign language have higher levels of achievement in foreign language.

People with lower levels of anxiety about learning a foreign language have higher levels of achievement in foreign language.

Explanation:

As you can see in the question above, a multiple regression analysis was used to explain anxiety in foreign languages as a predictor of success in foreign languages.

Multiple regression analysis is used whenever it is not possible to explain a phenomenon with just one variable. In the case of the question above, it was necessary to use predictive variables, including academic performance, perceived school competence and perceived self-worth.

In summary, this type of analysis allows a phenomenon to be explained by comparing several factors that influence the occurrence of that phenomenon. In the case of the question above, the value of the analysis was equal to -0.39, which allows us to conclude that people with lower levels of anxiety in learning a foreign language have higher levels of achievement in a foreign language.
