Question | Answer |

Box-and-Whisker | A diagram or graph using a number line to show the distribution of a set of data. The diagram displays the median, upper and lower quartiles, and the maximum and minimum values of the data. |
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. |
