| Bar Graph | A graph using vertical or horizontal bars to display numerical information |
| Pictograph | A graph using symbols to represent data |
| Line Graph | A graph in which a line shows changes in data, often over time |
| Circle Graph | A round graph that uses different sized wedges to show how portions of a set of data compare with the whole set |
| Scatter Plot | A graph showing paired data values |
| Trend | A relationship between two sets of data that shows up as a pattern in a scatterplot |

| Line Plot | A plot that shows the shape of a data set by stacking X's above each value on a number line |
| Scale | Ruler that measures the heights of the bars on a bar graph |
| Intervals | One of the equal-sized divisions on a bar graph scale |
| Horizontal Axis | The horizontal line of the two lines on which a graph is built |
| Vertical Axis | The vertical line of the two lines on which a graph is built |
| Stem-and-Leaf Diagram | A graph showing the shape of a data set by breaking each value into a "stem" part and a "leaf" part |
| Mean | The sum of the value in a data set divided by the number of values |
| Median | The middle value in a data set when the values are listed from least to greatest |
| Mode | The value(s) appearing most often in a data set |
| Outlier | A number very different from the other numbers in a data set |
| Range | The difference between the highest and lowest values in a data set |
| Histogram | A bar graph that uses ranges to show the frequency of different numerical values within a set of data |
