cor.test(A4Q1\(age, A4Q1\)education, method = “pearson”) cor.test(A4Q1\(age, A4Q1\)education, method = “spearman”)
A Pearson correlation was conducted to test the relationship between Variable 1 (M = 35.32634, SD = 11.45344) and Variable 2 (M = 13.82705, SD = 2.595901). There [was / was not] a statistically significant relationship between the two variables, r(df) =148, p = 9.113e-12. The relationship was positive/ negative and strong/ moderate/ weak. As the independent variable increased, the dependent variable increased/ decreased.
median(A4Q1\(education) mean(A4Q1\)education) sd(A4Q1\(education) median(A4Q1\)education)
A Spearman correlation was conducted to test the relationship between Variable 1 (Mdn =35.79811) and Variable 2 (Mdn =14.02915). There [was / was not] a statistically significant relationship between the two variables, ρ =0.5581, p =0.4385. The relationship was positive/ negative and strong/ moderate/ weak. As the independent variable increased, the dependent variable increased/ decreased. ```
