A researcher was interested in the effects of ‘hard’ and ‘soft’ human resource management practices on sales staff performance. Two similar sales teams from the same company were chosen, with one subjected to ‘hard HRM’ and the other to ‘soft HRM’. At the end of the quarter their sales figures were noted. The SPSS output is below. The experimenter made no predictions about which form of HRM would produce the best sales performance. What should he report?
A. Staff working under soft HRM sold significantly more than staff working under hard HRM, t(38) = 2.05, p< .05 B. Sales for staff working under soft HRM did not significantly differ from those for staff working under hard HRM, t(38) = 2.05, ns C. Staff working under soft HRM sold significantly more than staff working under hard HRM, t(23.12) = 2.05, p< .05, 1-tailed D. Sales for staff working under soft HRM did not significantly differ from those for staff working under hard HRM, t(23.12) = 2.05, ns.
