STATISTICS QUESTIONS AND
ANSWERS
rational number - ANSWER-A number that can be written as a
ratio of integers, which means it can be written as a fraction.
product - ANSWER-The result of multiplying values.
whole number - ANSWER-A number whose value is 0 or
greater and can be represented without a fractional or a
decimal component.
identity property - ANSWER-The property that 0 can be added
to any number without changing the value of the number.
Likewise, 1 can be multiplied by any number without changing
the value of that number.
associative property - ANSWER-The property that under certain
operations in a multi-step expression, the computations may be
done in any order. Commonly represented as (a + b) + c = a +

(b + c). Addition and multiplication both have this property, but
subtraction and division do not.
perfect square - ANSWER-The product of any integer with itself
yields this. So, a number is this if it can be written as the square
of an integer. For example, 9 is this because 3 * 3 = 9. Other
examples are 16, 25, 36, 49,...
set - ANSWER-In mathematics: a collection of numbers.
order of operations - ANSWER-A set of rules that defines the
order in which mathematical operations should be performed
multiplicative inverse - ANSWER-The number you must multiply
x by to get 1. For example, 5 and 1/5.
principal square root - ANSWER-The positive square root of a
number.

interval - ANSWER-A set of numbers between two specified
values.
operators - ANSWER-A word or symbol (such as + or -) that
indicates an operation between values.
commutative - ANSWER-The property that the order of the
numbers under the operation does not change the result.
Addition and multiplication have this property: a + b = b + a and
ab = ba.
radical sign - ANSWER-The symbol which indicates to take the
square root of the number that follows.
additive inverse - ANSWER-Two numbers equidistant from 0 on
a number line whose sum is 0. For example, 3 and -3.
greatest common factor (GCF) - ANSWER-The greatest
number that is both a factor of a and a factor of b.

factor tree - ANSWER-A graphical method used to identify the
prime factorization of an integer.
integer - ANSWER-A number, (positive, negative, or zero), that
can be represented without a fractional or a decimal
component.
discrete - ANSWER-A collection of numbers whose values are
distinct, separate, and unconnected.
prime factorization - ANSWER-Determining the set of prime
numbers whose product is the original integer.
continuous - ANSWER-A collection of numbers whose values
are not dividable into distinct units.
expressions - ANSWER-A string of terms that are connected by
division, addition, and subtraction operations.
quotient - ANSWER-The result of a division expression.
