Frame, sampling frame
| Glossary of Statistical Terms |
A sampling frame is a collection of units from which a sample will be drawn. ideally, the frame is identical to the population we want to learn about; more typically, the frame is only a subset of the population of interest. the difference between the frame and the population can be a source of bias in sampling design, if the parameter of interest has a different value for the frame than it does for the population. for example, one might desire to estimate the current annual average income of 1998 graduates of the university of california at berkeley. i propose to use the sample mean income of a sample of graduates drawn at random. to facilitate taking the sample and contacting the graduates to obtain income information from them, i might draw names at random from the list of 1998 graduates for whom the alumni association has an accurate current address. the population is the collection of 1998 graduates; the frame is those graduates who have current addresses on file with the alumni association. if there is a tendency for graduates with higher incomes to have up-to-date addresses on file with the alumni association, that would introduce a positive bias into the annual average income estimated from the sample by the sample mean.

Association, английский
- Ассоциация, объединение, союз
- Two variables are associated if some of the variability of one can be accounted for by the other. in a scatterplot of the two variables, if the scatter in the values of the variable plotted on the vertical axis is smaller in narrow ranges of the variable plotted on the horizontal axis (i.e., in vertical "slices") than it is overall, the two variables are associated. the correlation coefficient is a measure of linear association, which is a special case of association in which large values of one variable tend to occur with large values of the other, and small values of one tend to occur with small values of the other (positive association), or in which large values of one tend to occur with small values of the other, and vice versa (negative association).

Scatterplot, английский
A scatterplot is a way to visualize bivariate data. a scatterplot is a plot of pairs of measurements on a collection of "individuals" (which need not be people). for example, suppose we record the heights and weights of a group of 100 people. the scatterplot of those data would be 100 points. each point represents one person`s height and weight. in a scatterplot of weight against height, the x-coordinate of each point would be height of one person, the y-coordinate of that point would be the weight of the same person. in a scatterplot of height against weight, the x-coordinates would be the weights and the y-coordinates would be the heights.
Probability sample, английский
A sample drawn from a population using a random mechanism so that every element of the population has a known chance of ending up in the sample.
