Study Notes

Statistical Hypothesis Testing

  • Statistical significance is a measure of the probability that the observed difference between groups is due to chance.
  • The significance level is the maximum probability of rejecting a true null hypothesis, typically set at 0.05.
  • A result is considered statistically significant if the p-value is less than the significance level, indicating that the observed difference is unlikely to be due to chance.
  • The p-value represents the probability of obtaining the observed result (or a more extreme result) assuming that the null hypothesis is true.

Strategic Planning

  • Strategic planning lays the groundwork for effective project management.
  • Project managers use a top-down approach in the strategic view, focusing on overall goals and objectives.
  • The authors of the strategic models suggest that project managers initiate activities by issuing directives.
  • Organizing plans in a hierarchy allows for a clear understanding of how individual tasks contribute to the overall project goals.
  • The 'Game Plan' represents the overall strategy and approach for achieving project objectives.
