APPLIED HEALTHCARE STATISTICS
EXAM QUESTIONS AND 100%
CORRECT ANSWERS!!
An arrangement of values that illustrates their frequency or occurrence
Distribution
A graphical display that shows data in categories as percentages of a circle
Pie chart
A graph that displays data that is distributed over groups or categories
Bar chart
A way to approximate a percentage by dividing the number of times an event occurred
in an experiment by the total number of trials.
Relative frequency
A record of the number of times data occurs within a certain category
frequency distribution
A graphical representation of data that plots the frequency of data along a horizontal line
Dot plot
An observation point (number) that is significantly distant from the other observations in
the dataset
Outliers
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
, Stem plots
A graphical rendering of the range and the first and third quartiles of a data set with the
data set's median in between
Box plot
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
Measure of central tendency
A graph that displays data through vertical bars that show the counts or numbers in
each range
Histogram
The outline of a set of data displayed on the coordinate axes
Shape
The relationship between units and their visual representation on a graph
Scale
A structured form or table that allows data to be collected by marking how often an event
has occurred in a certain interval
Check sheet
< 50 divide data into 5-7 intervals
50-100 divide into 6-10 intervals
100-250 divide into 7-12 intervals
>250 divide into 10-20 intervals
Guides for histogram
The quality of the data having the same shape on both sides of the mean
Symmetry
