Q1) It is claimed that it's better to hire manager from outside a firm than promote one from within. A human resources analyst at firm justifies this claim by illustrating that average performance evaluations tend to be significantly higher for managers hired from outside firm compared with those promoted from within. Look at graph of salary versus performance evaluation in figure for managers at same level at firm is it true that average performance evaluation is higher for managers hired from outside firm compared with those promoted from within? What other stories does this graph tell?
