| Question | Answer |
|---|---|
| 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. |
| Dimension Lines | Lines that are thin lines capped with arrowheads, which may be broken along their length to provide space for the dimension numerals. |
| English System | Also referred to as the U.S. Customary system. The measuring system based on the foot, second, and pound as units of length, time, and weight or mass. |
| Extension Lines | Thin lines used to establish the extent of a dimension. Extension lines begin with a short space from the object and extend to about .125 inches past the last dimension line. |
| Foot | A unit of linear measure equal to 12 inches or 30.48 cm. |
| 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. |
| Inch | A unit of linear measure equal to one twelfth of a foot or 2.54 cm. |
| 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. |
| Meter | The fundamental unit of length in the metric system, equal to 100 centimeters or approximately 39.37 inches. |
| Metric System | The decimal measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass. |
| Millimeter | A metric unit of linear measure equal to 1/1000 of a meter. |
| 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. |
| Standard | Something considered by an authority or by general consent as a basis of comparison. |
| Statistics | Collection of methods for planning experiments, obtaining data, organizing, summarizing, presenting, analyzing, interpreting, and drawing conclusions based on data. |
| Two-Dimensional | Having the dimensions of height and width, height and depth, or width and depth only. |
| Unit | A standard quantity in terms of which other quantities may be expressed. |
| Variation | A change or slight difference in condition, amount, or level. |
