WebThere is no formula – it is just the middle term if you arrange the data in ascending order. Strictly, if there are n terms, count to the (n+1)/2 term. Mode Mode is the most frequently occurring value n the data. For continuous data, where every value is going to be slightly different, you need to specify a level of precision.
PERT formula is an approximation of the Beta Distribution equation. PERT is determined using three points: Optimistic (O), Most Likely (M), and Pessimistic (P). PERT combines probability theory and statistics to derive a formula for the average activity from the three-point estimates.
