| A | B |
|---|
| Stem | the greatest place value common to all the data that is written to the left of the line in a stem-and-leaf plot |
| Leaf | the units digit written to the right of the vertical line in stem-and-leaf plot |
| Frequency Table | a table for organizing a set of data that shows the number of times each item or number appears |
| Y-Axis | the vertical line of the two perpendicular number lines in a coordinate plane |
| Bar Graph | a graph using bars to compare quantities where the height or length of each bar represents a designated number |
| Coordinate System | a plane in which a horizontal number line and a vertical number line intersect at their zero points |
| Statistics | The study of collecting, analyzing, and presenting data |
| Lower Quartile | The median of the lower half of a set of data |
| Average | The sum of two or more quantities divided by the number of quantities; the mean |
| Box-and-Whiskers Plot | A diagram that summarizes data using the median, the upper and lower quartiles, and the extreme values |
| Ordered Pairs | a pair of numbers used to locate a point in the coordinate system |
| Y-Axis | The second number of an ordered pair |
| Mode | The number or item that appears most often in a set of data |
| Origin | the point of intersection of the x-axis and y-axis in a coordinate system |
| Upper Quartile | the median of the upper half of a set of numbers |
| X-Axis | the horizontal line of the two perpendicular number lines in a coordinate plane |
| Interval | the difference between the greatest number and the least number in a set of data |
| Stem-and-Leaf | a system used to condense a set of data where the greatest place value of the data forms the stem and the next greatest place value forms the leaves |
| Range | the difference between successive values on a scale |
| Measures | of the central tendency: numbers or pieces of data that can represent the whole set of data (mean,median, and mode) |
