| Bar Graph | a graph using horizontal or vertical 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 |
| Pie Graph | a round graph that uses different sized wedges to show how proportions of of data compare with the whole set |
| 2 Ways Graphs Are Misleading | No lables or some are missing, scale does not start at zero |
| Scatterplot | a graph showing paired data values |
| Trend | a relationship between two sets of data that shows up as a pattern in a scatterplot |
| Tally Marks | marks used to organize a large set of data |
| Frequency Chart | a table listing each value that appeares in a data set followed by the number of times it appears |
| Line Plot | a plot that shows the shape of a data set by stacking x's above each value on a number line |
| Scale | the "ruler" that measures the heights of bars in a bar graph |
| Interval | one of the equal sized divisions on a bar graph scale |
| Horizontal Axis | the horizontal line on the graph |
| Vertical Axis | the vertical line of the two lines on which the graph is built |
| Range | the difference between the highest and lowest values in a data set |
| Stem and Leaf Diagram | a graph showing the shape of a data set bt breaking each value into a "stem" part and a "leaf" part |
| Median | the middle value in a data set when the values are listed from lowest to highest |
| Mode | one of the values appearing most often in a data set |
| Mean | the sum of the values in a data set divided by the number of values; the average |
| Outlier | a number very different from the numbers in a data set |
