A line which represents distance |
|
dot plot |
See line plot |

|
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. |
|
mean |
A measure of center in a set of numerical data, computed by adding the values in a list and then dividing by the number of values in the list |
|
measure |
To determine the size, amount, or degree of an object by comparison with a standard unit |

A straight-edged strip of rigid material marked at regular intervals and used to measure distances. A proportion between two sets of dimensions used in developing accurate, larger or smaller prototypes, or models of design ideas |
|
scatter plot |
A graph in the coordinate plane representing a set of bi variate data |
|
significant digits |
