ra


Term: radian

(rA' dE un) n.

a unit of arc for which the arc length is equal to the radius of the circle. A radian is approximately equal to 57.296 degrees. SAS trigonometric functions use angles measured in radians.

Abbr. rad.

Term: radio box

(rA' di O boks) n.

a set of buttons, each representing a different option identified in an associated label, allowing a user to select one option from a set of option by selecting the button associated with that option. The selection of one button in a radio box causes all other buttons in the radio box to be deselected.

Term: radio button

(rA' di O but' n) n.

one of the buttons in a radio box.

Term: RAM

(ram') [random access memory] n.

ordinary memory that can be used by a program to contain the objects it creates and uses while it runs.

SAS word: RAND

Function.

Term: random access

direct access.

Term: random access memory

See RAM.

Term: random number

n.

1. a number selected randomly.

2. also, pseudo-random number. a number generated by a mathematical process (a random number generator) that simulates the essential qualities of a random number.

Term: random sample

n.

Term: range

(rAnj') n.

1. a set of values considered together, as in the definition of a format.

2. the set of values that may correctly be used for an array subscript.

3. the difference between the highest and lowest value in a sample.

4. a measure of the extent of a set of values.

5. the set of values that a function can return.

SAS word: RANGE

Term: rank

(rangk') v.t.

1. to arrange in order of magnitude, priority, etc.

n.
