| Line Plot | A graph that uses x above a number line each time that number occurs n a set of data |
| Population | A group o people (or objects or events) that fit a particular description. The entire group of items/individuals from which the samples under consideration are taken. |
| Sample | A number of people, objects or events chosen from a given population to represent the entire group. |
| Outlier | A number in a set of data that is much larger or smaller than most of the other numbers in the set. |
| Mode | The number or item that appears most often in a set of data. |
| Mean | The sum of the numbers in a set of data divided by the number of inputs; the arithmitic average. |
| Median | The number in the middle when the data is arranged in order. When there are two middle numbers, the median is their mean. |
| Range | The differnce between the greatest number and the least number in a set of data. |
| Line Graph | Most widely used graphs for showing changes over time are line graphs. |
| Multiple Line Graph | Similar to a line graph only multiple lines represent different sets of data. |
| Bar Graph | Lengths of solid bars to represent numbers and compare data. |
| Correlation | An association between two variables used in statistics. |
| Multiple Bar Graph | Bar graph with pairs of bars used to compare data when a regular bar graph is not appropriate. |
| Negative Correlation | realtionship between two sets of numerical data in which one set generally increases as the other decreases. |
