24 terms

Arc

Part of a circle from one point on the circle to another.

Area

The amount of surface inside a closed boundary. It is measured in square units, such as square feet or square centimeters.

Bar graph

A graph that uses vertical or horizontal bars to represent data.

Broken-line graph

A graph in which data points are connected by line segments. They often show how something has changed over time.

Circle graph

A graph in which a circle and its interior are divided by radii into parts. Sometimes called a "pie chart."

Stem and leaf plot

A data plot where digits with larger values are "stems" and smaller values are "leaves."

Graph key

A list that explains the symbols on a graph.

Double stem plot

The stem part of the graph has each number twice. the leaf part has two parts, one is 0-5, and the other one is 6-9.

Interior of a circle

The inside of the circle.

Landmark

Something that stands out in a data set. For example, the median, mode, minimum, maximum, and range of a data set.

Line plot

A graph that shows the frequency of data along a number line.

Maximum

The largest amount; the greatest number in a data set.

Minimum

The smallest amount; the smallest number in a data set.

Mode

The value or number that appears the most in a data set.

Mystery plot

An unlabeled graph or plot. The viewer is asked to give a situation that the plot or graph might represent.

Percent circle

A tool used to measure and draw figures that involve percents of circles.

Perimeter

The distance around a 2-dimensional shape along the border of the shape.

Precipitation

Rain, snow, or sleet are examples of this.

A line segment from the center of a circle to any point on the circle.

Random sample

A sample that gives all members of the population the same chance of being selected.

Sector

A region bound by an arc and two radii of a circle.

Side-by-side bar graph

Two bar graphs combined into one used to compare two sets of data.

Stacked bar graph

A bar graph where the categories of information in a graph are stacked on top of each other.

Step graph

A graph that looks like steps. The y values are the same for an interval of the x values.
