A psychologist was interested in whether a sense of "Job Autonomy" (a measure of how much freedom and discretion employees have over their job -higher scores on this measure correspond to more autonomy) could predict levels of Burnout among social workers. To study this, she collected data from five social workers, and conducted a regression analysis to predict levels of Burnout from Job Autonomy. Burnout was measured with a standard scale, where 1- low burnout and 10 high burnout (so,...
