A researcher conducted a study to investigate the relationship between anxiety, motivation, and writing performance. Multiple regression analysis was used to address: 1) how well anxiety and motivation predict writing performance, 2) which is the best predictor. Anxiety and motivation scores from 50 learners were collected via questionnaires and correlated with writing performance scores from essays. The regression model explained 15% of variance in writing performance, with anxiety making the largest unique contribution as the best predictor. Motivation's contribution was not statistically significant.
