Video Notes: Visualizing and Graphing Data - Key Concepts

Flashcards cover: one-variable vs two-variable data, what a relation is, ordered pair notation, domain and range concepts, expressing data as relations for several datasets (May–Oct temperatures, ball height, car distance), scatter plots, and recognizing a linear relation in the final graph.

What is one-variable data?

A list of values for a single variable (e.g., exam scores).

What is two-variable data?

A relationship between two data lists (e.g., month and average high temperature).

What is a relation in mathematics?

A set of ordered pairs (x, y).

What is the notation for an ordered pair?

(x, y).

What is the domain of a relation?

The set of all possible x-values.

What is the range of a relation?

The set of all possible y-values.

What is a scatter plot?

A graph with distinct plotted points representing a relation on a coordinate plane.
