Rational number (aka 'fractional')
Numbers that can be expressed as a fraction
Integers
Solid positive and negative numbers
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.
True or False? Any integer is also a whole number.
This statement is false. An integer can be negative, such as the number −100-100. −100-
100 is not a whole number.
Read all the options before answering. −17-17 is... (a. an integer b. a rational number c.
a real number d. all of the above.)
d. all of the above. −17-17 is an integer, and all integers are also rational numbers,
which in turn are real numbers.
, set
In mathematics, a collection of numbers is referred to as a set*
Interval
An interval is a set of numbers between two specified values. An interval can be
visualized as a segment of the number line. The segment of the number line above that
falls between 11 and 22 is called an interval*.
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 between each value.
In statistics, some data sets will be discrete. Examples 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 distinct groups.
