WGU Applied Healthcare Statistics Verified Questions
And Answers
whole numbers ANS Numbers that do not contain decimals or fractions
Integers ANS Whole numbers and their opposites
rational numbers ANS All positive and negative integers, fractions and decimal numbers.
Real numbers ANS Any number that can be placed on a number line. Including numbers that do not end,
and number like pi
A Set ANS A collection of numbers
Discrete ANS Values that are distinct, separate and unconnected
Continuous ANS Values in a set that are connected, without gaps
Quantitative Data ANS Consists of data values that are numerical, representing qualities that can be
counted or measured
Categorical data ANS Also called qualitative data. Consists of data that are groups, such as names or
labels, and are not necessarily numerical.
Graphical displays ANS Visual displays of data sets
data set ANS Any collection of numeric values, such as measurements, observations, or survey responses
Distribution ANS An arrangement of values that illustrates their frequency or occurrence
Pie chart ANS A graphical display that shows data in categories as percentages of a circle
, Bar chart ANS A graph that displays data that is distributed over groups or categories
Relative frequency ANS A way to approximate a percentage by dividing the number of times an event
occurred in an experiment by the total number of trials.
frequency distribution ANS A record of the number of times data occurs within a certain category
Dot plot ANS A graphical representation of data that plots the frequency of data along a horizontal line
Outliers ANS An observation point (number) that is significantly distant from the other observations in the
dataset
Stem plots ANS A visual representation of data in which individuals data points are plotted to the right of a
horizontal line, or chart, and the left (the "stem") shows the interval categories
Box plot ANS A graphical rendering of the range and the first and third quartiles of a data set with the data
set's median in between
Measure of central tendency ANS A summary measure that is used to describe an entire set of data with
one value that represents the middle or center of the data sets distribution. There are 3 main measures: mean,
median or mode
Histogram ANS A graph that displays data through vertical bars that show the counts or numbers in each
range
Shape ANS The outline of a set of data displayed on the coordinate axes
Scale ANS The relationship between units and their visual representation on a graph
Check sheet ANS A structured form or table that allows data to be collected by marking how often an
event has occurred in a certain interval
