| Scatter Plot | A data display in which ordered pairs are plotted on a coordinate plane. |
| Box and Whisker Plot | A data display in which information is shown based on five data points showing concentration and spread. |
| Measures of Central Tendency | values that tend to cluster around a certain value like mean, median and mode. |
| Histogram | This type of data display looks like a seamless bar graph, and it can be used with large data sets in conjunction with frequency tables. |
| Scale | The difference between the largest and smallest value on the axis. |
| interval | The difference between two numbers or between the hash marks on the axis or number line. |
| median | The middle number(s) of a data set. It is not subject to extremes. |
| mean | The average of a data set, and it is used to even out the distribution. It is subject to extremes. |
| range | The spread of a data set, or the largest value minus the smallest value of a data set. |
| Line graph | A data display that usually shows trends over time on a grid with a horizontal and vertical axis. |
| Circle graph | A pie chart that normally compares data that is part of a whole, like a budget. |
| frequency | The number of times that it occurs. |
| frequency table | A table that organizes frequencies, and it is useful for constructing histograms. |
| Line of best fit | A line that can be drawn on a scatter plot that matches the trend of the points. It can be linear, parabolic or exponential etc.. |
| upper extreme | The largest number in a data set, used in constructing box plots |
| lower extreme | the smallest number in a data set, used in constructing a box plot. |
| 1st or lower quartile | The midway point between the median and lower extreme of a data set. |
| 3rd or upper quartile | the point halfway between the upper extreme and the median. |
| data | Information that can be organized. |
| misrepresentation | Giving information that can mislead. For example you can change scales or use means instead of medians. |
