| A | B |
| arc | Part of a circle from one point on the circle to the other. |
| area | The number of square units required to cover a surface. |
| bar graph | A graph that uses horizontal or vertical bars to display data. |
| biased sample | A sample in which one or more parts of the population are favored over others. |
| box-and-whisker plot | Displays the spread of a data set using the 5 landmarks: min; lower quartile; median; upper quartile; max |
| broken-line graph | A graph where data points are connected by line segments. |
| circle graph | A graph using a circle which represents the whole. The interior is divided into parts. |
| double-stem plot | A stem-and-leaf plot in which each stem is split into two parts. |
| interquartile range (IQR) | The length of the interval between the lower and upper quartiles in a data set. |
| landmark | A notable feature of a data set; includes median |
| line graph | A graph that uses line segments to show changes that occur over time. |
| line plot | A number line with marks or dots that show frequency. |
| lower quartile | In an ordered data set |
| maximum | The largest amount; the greatest number in a set of data. |
| median | The middle number in a set of numbers that are listed in order. |
| minimum | The smallest amount; the smallest number in a set of data. |
| mode | The value(s) that occur the most often in a set of data. |
| percent circle | A tool on the geometry template that is used to measure and draw figures that involve percents. |
| perimeter | The distance around a closed 2 dimensional figure. |
| radius | The distance from the center of a circle to a point on the circle. |
| random sample | A sample in which every member in the population has an equal chance of being selected. |
| range | The difference between the greatest (max) and least (min) numbers in a set of data. |
| sample | A part of a group chosen to represent the whole group. |
| sector | The part of a circle that looks like a piece of pie. A sector is bounded by 2 radii and an arc of a circle. |
| side-by-side bar graph | Uses pairs of bars to compare two related data sets. |
| stacked bar graph | Bars are subdivided to show additional information. |
| stem & leaf plot | A display of data where digits with larger place values are "stems" and digits with smaller place values are "leaves. |
| upper quartile | The median of the upper half of a data set |
| lower quartile | The median of the lower half of a data set |
