Essential Mathematical Formulas for PMP Certification Test
A = B + C
Example
Assume you’re keeping track of the number of days it took to complete certain activities in a project:
– Task 1 took 5 days to complete.
– Task 2 took 8 days to complete.
– Task 3 took four days to complete.
– Task 4 took 7 days to complete.
– Task 5 took 6 days to complete.
To get the median, arrange these integers in the following order:
Four days, five days, six days, seven days, and eight days.
The median is the number that is exactly in the center. It’s 6 days in this example since it’s exactly in the center of the sorted list of days.
The median is useful in project management because it provides a concept of the midway value, which is beneficial when attempting to comprehend the usual or central value in a group of values. It is not impacted by extreme numbers like the mean (average), making it an excellent metric when your data contains outliers.
