Visual Displays of Data

These flashcards cover key concepts related to visual displays of data, including types of graphs, misleading techniques, and guidelines for effective graphing.

Visual Display of Data

Methods of presenting information that can accurately and succinctly present data, revealing or concealing complex information.

Misleading Graphs

Graphs that can distort information through various techniques, such as altering scales or misrepresenting data.

Biased Scale Lie

A technique used to mislead by altering the scale of the graph to emphasize or de-emphasize data.

Scatterplot

A graph that depicts the relationship between two scale variables, showing each data point.

Line Graph

A type of graph used to illustrate the relationship between two scale variables over time.

Bar Graph

A visual depiction showing the average value of a dependent variable grouped by categories of an independent variable.

Pie Chart

A circular graph that represents the proportion of each category of data as a slice of the pie.

Chartjunk

Unnecessary information or features in a graph that detract from the viewer’s ability to understand the data.

Pareto Chart

A type of bar graph in which categories are ordered from highest to lowest for easier comparison of values.

Line of Best Fit

A line drawn on a scatterplot to best represent the relationship between the variables.

Histogram

A bar-like graph displaying the frequency distribution of a scale variable, where bars represent intervals and touch each other.

Suppressing the Zero

A misleading graph technique where the y-axis does not start at zero, exaggerating differences between values.

Data-Ink Ratio

A principle of graph design advocating for maximizing the amount of 'data-ink' (ink used to display data) and minimizing 'non-data-ink'.
