Term | Definition |
Area | The number of square units it takes to completely fill a space or surface. |
Box and Whisker Plot | A diagram that summarizes data using the median, the upper and lowers quartiles, and the extreme values (minimum and maximum). |
Cubic Units | Measures the volume of solids |
Face | One of the polygons that make up a 3-dimensional figure. |
Inter-Quartile Range (IQR) | The difference between the first and third quartiles. (Note that the first quartile and third quartiles are sometimes called upper and lower quartiles.) |
Mean | The “average” or “fair share” value for the data; add all the numbers and divide by how many numbers there are. |
Measures of Center | Mean, median, and mode are used to summarize the middle of a data set with a single value. |
Median | The value for which half the numbers are larger and half are smaller. If there are two middle numbers, it is the arithmetic mean of the two middle numbers. |
Mode | The number that occurs the most often in a list. There can be more than one or none. |
Net | A 2-dimensional figure that, when folded, forms the surfaces of a 3-dimensional object. |
Outlier | A value that is very far away from most of the values in a data set. |
Polygon | A 2-dimensional closed shape with straight sides. |
Prism | A 3-dimensional figure with two parallel and congruent faces, called bases, and all other faces that are parallelograms. |
Range | The difference between the minimum and maximum value for a set of data. |
Surface Area | The total area of the 2-dimensional surfaces that make up a 3-dimensional figure. |
Volume | The amount of space occupied by a 3-dimensional object. |
Dot Plot | A diagram that displays data using circles or x's on a number line. |
Measures of Spread | Range and Interquartile Range are used to summarize the variability of a data set. |
Variability | Describes how spread out or closely clustered a set of a data is. |
Histogram | A diagram that displays the frequency of grouped data on a bar graph. |
