MEAN -> Average

MODE -> The “most found” number

RANGE -> Largest – Smallest Measure.

MEDIUM -> No in the middle or avg. of 2 middle Nos

STD. DEV. OF TASK = P – O
____________

_____________
CP STD. DEV. = √ σ² + σ² + σ²

SIGMA 1 = 68.26
2 = 95.46
3 = 99.73
6 = 99.99

Channels of Communication

PV (Present Value) = BCWS (Budgeted Cost of Work Schedule)

EV (Earned Value) = BCWP (Budgeted Cost of Work Performed)

AC (Actual Cost) = ACWP (Actual Cost of Work Performed)

CV = EV – AC

CPI = EV / AC (efficiency)

SV = EV – PV

SPI = EV / PV

ETC = BAC – EV or (BAC – EV) / CPI

EAC = AC + ETC

EAC = BAC / CPI

VAC = BAC – EAC

% COMPLETE = EV / BAC x 100

% SPENT = AC / BAC x 100

CV% = CV / EV x 100

SV% = SV / PV x 100
