The term "mass" is always used in the strict Newtonian sense as a property intrinsic to matter.  It differs from weight in that weight can vary, but mass does not.   In other words, mass is a quantity of matter.		References in this course: M2L1T2, p. 1/32
The apparent mass vs. 8.0 gram per cubic centimeter  of an object is defined as the mass the object would "appear" to have if it were compared against a standard which has the density of 8.0 gram per cubic centimeter.  It is a mass giving the same balance reading as the object when the comparison is made at 20 C in air having a density of 1.2 milligram per cubic centimeter.

The conventional mass value of a body is equal to the mass, Mc, of a standard that balances this body at conventionally chosen conditions.  The unit of the defined quantity "conventional mass" is the kilogram.		References in this course: M2L1T2, p. 20/32
In mass measurement, the term "true mass" is used to mean the mass of an object; the property intrinsic to matter.		References in this course: M2L1T2, p. 27/32
Maximum Permissible Error (MPE) or Tolerance is the maximum amount by which the conventional mass of the weight is allowed to deviate from the assigned nominal value.  (It is also called allowable inaccuracy or error.)		References in this course: M3L5T2, p. 9/24
The mean is the calculated value of the sum of the data points divided by the number of data points.		References in this course: M1L2T2, p. 6/32
Measurement assurance is a process that uses good experimental design principles and includes complete characterization of the measurement uncertainty and continuous monitoring of the performance of the measurement process.		References in this course: M3L1T2, P.3/29
The median is the central point in a list of the data arranged in either ascending or descending order.  Half of the data is less than or equal to the median and half is more than or equal to the median.  For an even number of data points, it is the mean of the two middle data points.

The mode is the value that occurs most frequently.		References in this course: M1L2T2, p. 6/32
