Question | Answer |
---|---|
Class | is a set of #s or things |
Range | is the interval(space in between)spanned by the data. is the difference between the largest and the smallest # in a distribution |
Class interval | is a range of scores |
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 |
Median | is the middle number of a ranked group |
Distribution | arrangement of numbers 分布 |
Quartiles | there are three quartile designations (first, second, and third), which correspond to the 25th, 50th, 75th percentiles. |
The second quartile | is the 50th percentile, which extends to the median, or midpoint of the distribution |
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 |
Maternal death | Death of any woman while pregnant or within 42 days of termination of pregnancy |
Infant death | death of a liveborn infant < 1 yr of age |

Life span | the length of life |
Tabulate | shaped like a table or tablet 制表 |
Gestation | from Latin - to bear. The period of fetal development from conception until birth; pregnancy. 妊娠 |
Still born/Fetal death | a still born is classified as a fetal death |
