STATISTICS EXAM QUESTIONS AND
ANSWERS 2025
Rational number (aka 'fractional') - ANSWERSNumbers that can be expressed as a
fraction
Integers - ANSWERSSolid positive and negative numbers
Real Numbers - ANSWERSA 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. - ANSWERSThis 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.) - ANSWERSd. all of the above. −17-17 is an integer,
and all integers are also rational numbers, which in turn are real numbers.
set - ANSWERSIn mathematics, a collection of numbers is referred to as a set*
Interval - ANSWERSAn 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 - ANSWERSCan 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 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 - ANSWERSCan 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 example of continuous data might be age. It is possible to be
22.6722.67 years old. Real numbers are considered continuous.)
00, 11, 22 is a set of continuous data. True or False? - ANSWERSFalse. This statement
is false. 00, 11, and 22 are distinct consecutive integers. There are numbers, such as
1.51.5, between them, so they are not continuous.
emperature is an example of continuous data. True or False? - ANSWERSThis
statement is true. Temperature covers an entire interval of data and can be "measured"
rather than counted, so it is continuous.
Timesheets log the days that a nurse works each week. Does the week's timesheet give
data that is discrete or continuous? - ANSWERSDiscrete. The days of the week are
discrete and do not allow for values between them.
A graph shows the efficacy of a particular drug at different dosages. Is this data discrete
or continuous? - ANSWERSDiscrete. The graph shows discrete drug dosages, not all
possible dosages, between two numbers.
During a physical, the nurse records the patient's age, weight, and height. Are these
data discrete or continuous? - ANSWERSContinuous. These are all continuous
measurements for which it is possible to have fractional parts.
< - ANSWERS"less than"
> - ANSWERS"greater than"
≤ - ANSWERSless than or equal to
≥ - ANSWERSgreater than or equal to
Which of the following is the correct translation of −3<y<4-3<y<4? - ANSWERS−3-3 is
less than y which is less than 4 (Both of the << symbols mean "less than," so the correct
translation is −3-3 is less than y which is less than 4.)
