Definition

Statistic – A quantity calculated from a sample of observations, usually as an estimate of some population parameter such as mean or standard deviation. AGARD Multilingual Aeronautical Dictionary, 1980.

Probability – A real number in the scale 0-1 attached to a random event. It can be related to a long run relative frequency of occurrence or degrees of belief that an event will occur. AGARD Multilingual Aeronautical Dictionary, 1980.

NASA Interest

Exhaustive Interest : All statistical and probability theory, sampling techniques, reliability theory and techniques related to aerospace activities, aircraft and spacecraft control, facilities, development, and manufacturing.

Selective Interest : Statistics and probability related to transportation, agriculture, water pollution, and air pollution of possible aerospace interest or application.

Negative Interest : Statistics and probability concerned with banking, housing, home furnishing, and general manufacturing of a nonaerospace nature.
