What is a Scatter Plot?

Back

A graph that displays individual data points and is useful for visualizing general trends.

Front

What is a Two-Way Frequency Table?

Back

A table that shows the frequency of different combinations of two categorical variables, useful for finding joint and marginal frequencies.

Front

What is a Line Graph?

Back

A graph that displays data points connected by lines, useful for showing changes over time.

Front

What is a Histogram?

Back

A graphical representation of the distribution of numerical data, showing the frequency of data points within specified ranges.

Front

What is a Box Plot?

Back

A graph that summarizes data using the median, quartiles, and extremes, but does not show individual data points or clusters.

Front

What is a Dot Plot?

Back

A simple graph that displays individual data points as dots along a number line, but can be difficult to read with large data sets.

Front

What is a Circle Graph (Pie Chart)?

Back

A circular graph divided into slices to illustrate numerical proportions, but not suitable for showing trends.

Front

What are Marginal Frequencies?

Back

The totals of the rows and columns in a two-way frequency table, showing the overall frequency of each category.

Front

What are Joint Frequencies?

Back

The frequencies that represent the intersection of two categories in a two-way frequency table.

Front

What is the purpose of a Bar Graph?

Back

A graph that uses bars to compare different categories of data, useful for showing quantities.
