|
A line which represents distance.
|
|
|
Dot 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.
|
|
|
Frequency |
The rate at which something occurs over a particular period or in a given sample. |

|
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.
|
|
|
Scatter Plot
|
A graph in the coordinate plane representing a set of bivariate data.
|
|
|

|
The digits in a decimal number that carry meaning contributing to the precision or accuracy of the quantity.
|
|
|
Standard Deviation
|
The distance of a value in a population (or sample) from the mean value of the population (or sample).
|
|
|
Statistics
|
Collection of methods for planning experiments, obtaining data, organizing, summarizing, presenting, analyzing, interpreting, and drawing conclusions based on data. |
