| Central Tendency | Refers to the average of a data set, includes mean, median and mode. |
| Data Distribution | Takes into account the range and spread of a data set. It describes the shape of a data set when displayed on a histogram or dot plot. |
| Dot Plot | A number line long enough to encompass all numbers in a sample, showing a dot over the position corresponding to each number. |
| Interquartile Range | A measure of spread equal to the upper quartile (Q3) minus the lower quartile (Q1) in a data set. |
| Lower Quartile Range | Quartile 1 (Q1) is the median of the lower half of the values. |
| Maximum Value | Highest or greatest amount or value. |
| Mean | The total of all the scores or amounts, divided by, how many scores or amounts there were. |
| Median | A type of average which is the middle value of an ordered set of data values. |
| Minimum Value | Smallest or least amount or value. |
| Outlier | A value far away from most of the rest in a set of data. |
| Range | The difference between the lowest and highest values in a data set. |
| Skewed Distribution | The distribution of negatively skewed data tails off to the left towards the minimum value. The distribution of positively skewed data tails off to the right towards the maximum value. |
| Upper Quartile | Quartile 3 (Q3) is the median of the upper half of the values. |
