stat Flashcards
a ubiquitous tool used in
business for basic data visualization. Makes it easy
for anyone to create standard examples of data
visualization.
Microsoft Excel
one of the most helpful idea for
creating effective tables and charts for data visualization
- First described by Edward R. Tufte in 2001 in his book The Visual Display of Quantitative Information
Data-Ink Ratio
the ink used in a table or chart that is
necessary to convey the meaning of the data to the
audience.
Data-ink
ink used in a table or chart that
serves no useful purpose in conveying the data to audience.
Non-data-ink
known as a crosstabulation in
Microsoft Excel
PivotTable
– Excel pairs with PivotTables to
summarize and analyse data with both
crosstabulation and charting.
PivotCharts
is a clustered-column chart whose
column heights correspond to the average wait times
and are clustered into the categorical groupings of
Good, Very Good, and Excellent.
PivotChart
Type of helpful chart for examining data with more than 2 variables.
- Includes a different vertical axis for eachvariable.
Parallel-coordinate plot
represents the value taken by that observation for variable corresponding to the vertical axis.
The height of the line on each vertical axis
useful for visualizing hierarchical data
along multiple dimensions
Treemap
Which merges maps and statistics to present data collected over different geographic areas. Displaying geographic data on a mapcan often help in interpreting data andobserving patterns
Geographic Information Systems (GIS)
allows the user to create interactive GIS-
type charts. This tool is quite powerful, and the ful lcapabilities are beyond the scope of this versions

3D Map
A graphical presentation that uses
horizontal bars to display the magnitude ofquantitative data. Each bar typically represents a class of a categorical variable.
Bar Chart
A graphical presentation used to
visualize three variables in a two-dimensional graph. The two axes represent two variables, and themagnitude of the third variable is given by the size of
the bubble.
Bubble Chart
A visual method for displaying data; also
called a graph or a figure.
Chart
special type of column (bar) chart in which multiple bars are clustered in the same class to compare multiple variables; also known as a side-by-side- column (bar) chart.
Clustered-column (or clustered-bar) chart
A graphical presentation that uses
vertical bars to display the magnitude of quantitative data. Each bar typically represents a class of a
categorical variable.
Column Chart
A tabular summary of data for
two variables. The classes of one variable are represented by the rows; the classes for the other variable are represented by the columns.
crosstabulation
A data-visualization tool that
updates in real time and gives multiple output
Data dashboard
- A system that merges maps and statistics to present data collected over different geographies.
Geographic information system (GIS)
- A two-dimensional graphical
presentation of data in which color shadings indicate magnitudes.
Heat Map
- A metric that is crucial for understanding the current performance of an organization; also known as a key performance
metric (KPM).
Key performance indicator (KPI)
A graphical presentation of time series
data in which the data points are connected by a line.
Line Chart
A graphical presentation used to
compare categorical data. Because of difficulties in comparing relative areas on a pie chart, these charts are not recommended. Bar or column charts are generally superior to pie charts for comparing categorical data.
Pie Chart
- A graphical presentation of the
relationship between two quantitative variables. One variable is shown on the horizontal axis and the other on the vertical axis
Scatter Chart
- A graphical presentation that
uses multiple scatter charts arranged as a matrix to illustrate the relationships among multiple variables.
Scatter-chart matrix
A special type of line chart that indicates
the trend of data but not magnitude. does not include axes or labels.
Sparkline
A special type of column
(bar) chart in which multiple variables appear on the
same bar.
Stacked-column Chart
A line that provides an approximation of
the relationship between variables in a chart.
Trendline
