Front 16

Line Plot

Back 16

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

Front 17

Mean

Back 17

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.

Front 18

Standard deviation

Back 18

The distance of the value in a population (or sample) from the mean value of the population (or sample).

Front 19

Statistics

Back 19

Collection of methods for planning experiments, obtaining data, organizing, summarizing, presenting, analyzing, interpreting, and drawing conclusions based on data.

Front 20

Unit

Back 20

A standard quantity in terms of which other quantities may be expressed.

Front 21

US customary measurement system

Back 21

System of measurement use in the United States

Front 22

Variation

Back 22

A change or slight difference in condition, amount, or level.

Front 23

Measure

Back 23

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

Front 24

Median

Back 24

A measure of center and a set of numerical data. The median of a list of values is the value appearing at the center of a sorted version of the list- or do you mean of the two central values at the list contains an even number of values

Back 27

A number value or algebraic equation that is used to control the size or location of a geometric figure.

Front 28

Precision

Back 28

The degree to which repeated measurements show the same result.

Front 29

Scale

Back 29

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

Back 30

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

Front 31

Significant digits

Back 31

The digits in a decimal number that carry meaning contributing to the precision or accuracy of the quantity.
