Data Visualization

Question 1

Bar chart

Answer 1

A graphical presentation that uses horizontal bars to display the magnitude of quantitative data. Each bar typically represents a class of a categorical variable.

Question 2

Bubble chart

Answer 2

A graphical presentation used to visualize three variables in a two-dimensional graph. The two axes represent two variables, and the magnitude of the third variable is given by the size of the bubble.

Question 3

Chart; graph; figure

Answer 3

A visual methods for displaying data

Question 4

Clustered column chart

Answer 4

A 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-sidecolumn (bar) chart.

Question 5

Column chart

Answer 5

A graphical presentation that uses vertical bars to display the magnitude of quantitative data. Each bar typically represents a class of a categorical variable.

Question 6

Crosstabulation

Answer 6

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.

Question 7

Data dashboard

Answer 7

A data-visualization tool that updates in real time and gives multiple outputs.

Question 8

Data-ink ratio

Answer 8

The ratio of the amount of ink used in a table or chart that is necessary to convey information to the total amount of ink used in the table and chart.

Question 9

Geographic Information System (GIS)

Answer 9

A system that merges maps and statistics to present data collected over different geographies.

Question 10

Heat map

Answer 10

A two-dimensional graphical presentation of data in which color shadings indicate magnitudes.

Question 11

Key performance indicator; key performance metric

Answer 11

A metric that is crucial for understanding the current performance of an organization

Question 12

Line chart

Answer 12

A graphical presentation of time series data in which the data points are connected by a line.

Question 13

Parallel-coordinates plot

Answer 13

A graphical presentation used to examine more than two variables in which each variable is represented by a different vertical axis. Each observation in a data set is plotted by drawing a line between the values of each variable for the observation.

Question 14

Pie chart

Answer 14

A graphical presentation used to compare categorical data as a relative fraction of the whole amount

Question 15

PivotChart

Answer 15

An interactive graphical presentation created in Excel

Question 16

PivotTable

Answer 16

An interactive crosstabulation created in Excel

Question 17

Scatter chart

Answer 17

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.

Question 18

Scatter chart matrix

Answer 18

A graphical presentation that uses multiple scatter charts arranged as a matrix to illustrate the relationships among multiple variables.

Question 19

Sparkline

Answer 19

A special type of line chart that indicates the trend of data but not magnitude; it does not include axes or labels.

Question 20

Stacked column chart

Answer 20

A special type of column (bar) chart in which multiple variables appear on the same bar.

Question 21

Treemap

Answer 21

A graphical presentation that is useful for visualizing hierarchical data along multiple dimensions. It groups data according to the classes of a categorical variable and uses rectangles whose size relates to the magnitude of a quantitative variable.

Question 22

Trendline

Answer 22

A line that provides an approximation of the relationship between variables in a chart.
