denominator

In a fraction, the number on the bottom.

difference

The result when values are subtracted.

numerator

In a fraction, the number on the top.

product

The result when values are multiplied.

quotient

The result when values are divided.

sum

The result when values are added.

exponent

Indicates that the base value should be multiplied times itself for each value of the exponent. A negative exponent indicates the fraction of 1 over the base times itself for each value in the exponent.

root

The divisor that times itself by the value of the root will equal the number.

scientific notation

A method of writing numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10. Scientific notation is useful for expressing very small and very large values.

significant digits

The number of digits required for the specified degree of accuracy or precision. Leading and trailing zeros are not considered in determining significant figures except where the trailing zeros are after the decimal.

common cause variation

Inherent but random fluctuations in a process output.

control chart

Graphic tool used in Statistical Process Control to display process data along with established limits for variation in a process including the central tendency or target, upper control limit (UCL), and lower control limit (LCL).

lower control limit

The minimum variation in process data that is statistically likely to occur if a process is in control.

process variable

Anything in a process that is measured.

set point

A target value for a process variable.

Statistical Process Control

A quality control process that uses data from sampling, customer and manufacturing specifications and analytical data to track the quality of a product during production. SPC uses tools such as control charts to track data and determine if a process is producing predictable results.

upper control limit

The maximum variation in process data that is statistically likely to occur if a process is in control.
