Back

Frequency distribution

Front

A table that shows how many times the numbers in each interval occur in the data.

Back

Numerical expression

Front

A type of statistical graph in which a "box" encloses the middle half of the data set and "whiskers" extend to the minimum and maximum data values.

Back

Exponent

Front

The number or variable that represents the number of times the base of a power is used as a factor.

Back

Term

Front

For an expression such as 2x+1, the parts are added together, 2x and 1, are called terms.
