General Characteristics

  • The Beta distribution curve can take a variety of shapes; asymmetrical shapes, symmetrical half circle and/or inverted or cup-up half circle.

 

Specific Characteristics

Key Measures:

Shape1 (S1), Shape2 (S2)

 

Range of values:

0 < x < 1

 

Mean:

Mean = (Shape1) / (Shape1 + Shape2)
Mean = S1 / (S1 + S2)

 

Standard Deviation, SD:

SD = √[(S1 * S2) / ((S1 + S2)² * (S1 + S2 + 1))]

 

Application

Beta distributions can be used; to calculate the time required to complete a task & as an approximation in the absence of data.
