| 7275323923 | Simpson's Paradox | a reversal of the direction of a comparison or an association when data from several groups are combined to form a single group, and vise versa | 0 | |
| 7282660290 | Histogram | a bar graph representing quantitative values and frequency | 1 | |
| 7282682887 | Dotplot | places a dot along an axis for each case in the data instead of a bar | 2 | |
| 7282704615 | Describe distributions by commenting on | center, unusual features, shape and spread | 3 | |
| 7282709443 | CUSS | Center, Unusualness, shape, spread | 4 | |
| 7282715336 | center | a numerical value that attempts to summarize the approximate typical value of the distribution | 5 | |
| 7282728608 | unusual features | you should always mention any straggler (outliers) that stand off from the body of the distribution. If any gaps are present in the distribution, we might have data from more than one group. | 6 | |
| 7282747802 | shape | 7 | ||
| 7282749525 | unimodal | a histogram with one main peak | 8 | |
| 7282750932 | bimodal | a histogram with two main peaks | 9 | |
| 7282756625 | uniform | a distribution with no mode; roughly flat | 10 | |
| 7282771104 | symmetric distribution | when right and left sides are mirror images of each other | 11 | |
| 7282777670 | Skewed to the right | when the tail of a histogram is on the right | 12 | |
| 7282779008 | skewed to the left | when the tail of a histogram is to the left | 13 | |
| 7282793978 | range | highest numerical value minus the lowest | 14 | |
| 7290185108 | Stem Plots | Vertical Histograms constructed by first cutting each data value into leading digits (stems) and trailing digit (leaf), use only one digit for each leaf |  | 15 |
