QUESTIONS AND ANSWERS
1. Rational number (aka Numbers that can be expressed as a fraction
'fractional')
2.
Integers Solid positive and negative numbers
3.
Real Numbers
A real number is any number that can be placed
on the number line, whether that be negative or
positive, fraction or decimal.
4. True or False? Any
in-teger is also a
whole number.
5. Read all the op-tions
before answer-ing. 17-
17 is... (a. an integer b.
a rational number c. a
real num-ber d. all of
the above.)
6. set
7. Interval
This statement is false. An integer can be negative,
such as the number 100-100. 100-100 is not a
whole number.
d. all of the above. 17-17 is an integer, and all in-
tegers are also rational numbers, which in turn
are real numbers.
In mathematics, a collection of numbers is
referred to as a set*
An interval is a set of numbers between two speci-
fied values. An interval can be visualized as a seg-
ment of the number line. The segment of the
number line above that falls between 11 and 22 is
called an interval*.
8. Discrete data Can only have certain, distinct values
Is "counted"
Contains unconnected points
In mathematics, whole numbers, integers, and even
integers are all examples of discrete sets. These
sets contain unconnected elements, with gaps be-
tween each value.
In statistics, some data sets will be discrete. Exam-
ples of discrete data sets are the number of adults
in a household, the results of rolling two dice, and
number of machines in operation, as these are dis-
