C784-Applied Healthcare Statistics Exam
Questions and Answers
Rational number (aka 'fractional') - Correct Answer
✅Numbers that can be expressed as a fraction
Integers - Correct Answer ✅Solid positive and negative
numbers
Real Numbers - Correct Answer ✅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. - Correct
Answer ✅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.) - Correct Answer ✅d. all of the above. −17-17 is an
integer, and all integers are also rational numbers, which in
turn are real numbers.

Questions and Answers
set - Correct Answer ✅In mathematics, a collection of
numbers is referred to as a set*
Interval - Correct Answer ✅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 - Correct Answer ✅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.
(Looking at another set of data, consider the number of cars
someone owns. It is not possible to own 3.43.4 cars; you
, C784-Applied Healthcare Statistics Exam
Questions and Answers
either own three cars or four. The number of cars someone
owns is an example of a discrete set of data, since the values
are distinct, separate, and unconnected. Positive integers*
are an example of discrete data.)
Continuous data - Correct Answer ✅Can have any value
within an interval
Is "measured"
Does not have clear boundaries between elements or data
points
In mathematics, the set of real numbers is an example of a
continuous set. This sets contains continuous elements, with
no discernible gaps between each element. Remember that
the number line is a visual representation of the set of real
numbers. Just as the number line is continuous with no gaps,
so is the set of real numbers.
In statistics, some data sets will be continuous. Examples of
continuous data sets are temperature, distance, and time, as
the set of possible values within these groups is continuous.
An element in these groups can hold any real number within
a certain interval, dependent upon the scale used. (A set of
data is continuous if it can hold any value within the set. An
