Practice with correlation coefficients Using the table that appears below each pair of variables, please state the direction and strength (using Cohen’s rules of thumb) of each correlation coefficient, r. Assume all coefficients are statistically significant at p < .05. Then, interpret the correlation. Please describe the pattern, conceptually, without using the word “correlated” in your description. Finally, explain why you can or cannot infer a causal relationship between the two variables. 1. Academic performance, anxiety: r = -.22 Direction & strength: __________________________________________________ Interpretation: __________________________________________________________ Can you infer causality? Explain. __________________________________________
