| Data Set | A group of individual values or bits of information that are related in some way or have some common characteristic or attribute. |
| Dimension | A measurable extent, such as the three principal dimensions of an object is width, height, and depth. Length and thickness are not used because they cannont be applied in all cases. The front view of an object shows only the height and width and not the depth. In fact, any one view of a three-dimensional object can show only two dimensions, the third dimension will be found in an adjacent view. |
| Dimension Lines | Lines that are thin lines capped with arrowheads, which may be broken along their length to provide space for the dimension numerals. |
| Frequency | The rate at which something occurs over a particular period or in a given sample. |
| Graph | A diagram showing the relation between variable quantities, typically of two variables measured along a pair of lines at right angles. |
| Histogram | A graph of vertical bars representing the frequency distribution of a set of data. |
| International Organization for Standardization (ISO) | A non-governmental global organization whose principal activity is the development of technical standards through consensus. |
| Mean | The average or central value of a set of quantities. |
| Measure | To determine the size, amount, or degree of something by comparison with a standard unit. |
| Median | Referring to the middle term or mean of the middle two terms of a series of values arranged in order of magnitude. |
| Mode | The value that occurs most frequently in a given data set. |
| Normal Distribution | A function that represents the distribution of variables as a symmetrical bell-shaped graph. |
| Numeric Constraint | A number value, or algebraic equation that is used to control the size or location of a geometric figure. |
| Precision | Exact in measuring, recording, etc. |
| Scale | 1. A straight-edged strip of rigid material marked at regular intervals and used to measure distances. 2. A proportion between two sets of dimensions used in developing accurate, larger or smaller prototypes, or models of design ideas. |
| Line Plot | A method of visually displaying a distribution of data values where each data value is shown as a dot or mark above a number line. Also known as a dot plot. |
| Accuracy | The degree of closeness of measurements of a quantity to the actual (or accepted) value. |
| Arrowheads | These are used to indicate the end of a dimension line or leader. |
| Caliper | A measuring instrument having two adjustable jaws typically used to measure diameter or thickness. |
| Class Interval | A group of values that is used to analyze the distribution of data. |
| Convert | To change money, stocks, or units in which a quantity is expressed into others of a different kind. |
