Locus of Control as a Predictor of Career Decision-Making Among Young Adults in Medan
Abstract
This study aims to determine the relationship between internal locus of control and career choice among 11th-grade students at State Senior High School 14, Medan. A quantitative correlational design was employed. The population comprised all 11th-grade students at State Senior High School 14, Medan, from which a sample of 187 students was drawn using proportionate stratified random sampling across ten classes. Data were collected through a career-choice questionnaire and an internal locus of control questionnaire, both developed on a four-point Likert scale. The results showed that the residual data were normally distributed (Asymp. Sig.=0.200 > 0.05) and linearly related (Sig. Linearity = 0.000 < 0.05). The correlation coefficient obtained was r = 0.723 with a significance value (Sig., 2-tailed) of 0.000 (< 0.05), indicating a significant, positive, and strong relationship between internal locus of control and career choice, with a coefficient of determination of 52.27%.
