are not necessarily numerical.
, Categorical data

Graphical displays
Any collection of numeric values, such as measurements, observations, or survey responses
data set

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
