|
Line Plot
|
A method of visually displaying a distribution I data values where each data value is shown as a dot or mark above a number line. Also known as dot plot
|
|
Mean
|
A measure of center in the set of numerical data, computed by adding the values in a list and then dividing by the number of values in the list.
|
|
Standard deviation
|
The distance of the 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.

|
Measure
|
To determine the size, amount, or degree of an object by comparing with the standard unit

|
Precision
|
The degree to which repeated measurements show the same result.
|
|
Scale
|
One. A straight-edge strip of rigid material marked at regular intervals and used to measure distances. Two. A proportion between two sets of dimensions used in developing accurate, larger smaller prototypes, or models of design ideas.
|
|
Scatter plot
|
A graph in the coordinate plane representing a set of bivariate data.
|
|
Significant digits
|
The digits in a decimal number that carry meaning contributing to the precision or accuracy of the quantity.
