Sample Solution

GNU PSPP is a program for statistical analysis of sampled data. It is a free as in freedom replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most of these exceptions are, there are no “time bombs,” your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functions that PSPP currently support is in the core package. It can perform descriptive statistics.

rtance of establishing a hierarchy became evident during the planning stage of the outdoor management course for the red team, the coordinators within the team assumed leadership roles but were unable to gain positional power due to the team being a peer group (Pettinger, 2007). The leaders selected had little authority and influence over the group as everyone was perceived to have the same rank, status and occupation, hence the leaders had none of French and Ravens five bases of power (Pettinger, 2007). The result was leaders with no positional power over the group, so could not direct the group with the method of leadership required for the situation. The task had significant constraints, particularly a short time frame and a large group size, for this situation Chelladurai recommends an autocratic leadership style would be most favourable (Chelladurai and Madella, 2006). The leaders attempted an autocratic leadership style, setting individual tasks for the group, however due to the poor leader member relations and lack of positional power the leadership structure quickly became a democracy. The product was an extremely unproductive workforce initially because of the time spent discussing how was best to approach the task. Because of how the leaders were perceived by the group there was little mutual trust, respect or confidence that the leaders were making the correct decisions, and as a result any management style they tried to implement would have been unsuccessful (Pettinger, 2007). Ultimately, if the leaders had analysed their position and the group they would have realised this and chosen a more democratic approach initially the group would have gained trust for the leaders, making future policy implementation easier.
