| Frequency | is the # of times a certain score appears in the distribution 频率 |
| Rank | means a number's position in a group when all scores have been arranged in order of size |

| Deciles | the data set can be divided into ten equal parts called deciles |
| the first decile | 1/10 or 10% of the data in the distribution, the 2nd decile is 20% and so on. |
| How many deciles are there? | There are 10 deciles: 10th, 20th, 30th and so on. |
| Centiles/Percentiles | Centiles and Percentiles are the same |
| Percentiles | divide the distribution into 100 equal segments |
| Cumulative frequency | is by adding each frequency to the previous frequency and accumulating frequencies from one end of the frequency to the other. |
| The number of scores between each percentile | is equal |
| The score ranges between percentiles | may not be equal |

| Life span | the length of life |
