How is the project mean calculated in statistical sums?

  1. Sum of the modes of the individual tasks

  2. Sum of the medians of the individual tasks

  3. Sum of the means of the individual tasks

  4. Sum of the variances of the individual tasks

The correct answer is: Sum of the means of the individual tasks

The project mean is calculated by finding the sum of the means of the individual tasks. This is because the mean is a measure of central tendency that takes into account all data points, making it a more accurate representation of the project's overall performance. A, B, and D are not correct because they either focus on specific data points (modes, medians) or measure the spread of data (variances), which do not accurately represent the overall performance of the project.
