When Using the Beta Distribution for Estimating Activity Times

question 100

Multiple Choice

When using the beta distribution for estimating activity times,

• A) the most likely time estimate can be positioned anywhere between the optimistic and pessimistic time estimates.
• B) the most likely time estimate becomes the mean of the distribution.
• C) we assume that the standard deviation is one- third the range between the optimistic and pessimistic time estimates.
• D) an advantage is that the mode of the distribution is always equidistant from the end points of the distribution.

Definitions:

Gate Control Theory

A theory suggesting that psychological factors play a role in the perception of pain, proposing that pain signals pass through neural "gates" in the spinal cord that can modulate pain intensity.

Pain Sensations

The feelings or perceptions produced by stimulation of nerve endings, often signaling harm or potential injury.

Neural Gate

A theoretical mechanism within the nervous system thought to control the passage of pain signals to the brain.

Signal Inhibition

A process by which neural activity is reduced or stopped, leading to the decrease or cessation of a physiological response or signal transmission.
