|
Term
| observational study or survey |

Definition
| the collection of data about persons or obejcts by merely recording information about selected characteristics of interest (such as A or B), while paying no attention to possibly widely diverging other characteristics (such as C or D) that may affect the chosen characteristics |
|
|
Term
|
Definition
| numbers that label differences in kind, as nominal data do, but that, in addition by their very size also order or rank observations on the basis of importance |

Term
|
Definition
| the set of all possible observations about a specified characteristic of interest |

|
Term
|
Definition
