A type of frequency graph that is constructed by connecting dots by a single line. The resulting figure is a multi-sided figure.
Polygon
The width of an interval that is used in constructing a frequency table or histogram
Bin width

Letter value display
Frequency data that are displayed in bins or intervals
Grouped data
The degree to which numbers differ from central tendency
Variability
A measure of variability in which squared deviation from the mean are averaged
Standard Deviation
An average in which a certain portion of numbers are deleted from the highest and lowest ends of an ordered batch of data
Trimmed Mean
Using symbols to represent different ranges of data based on letter value display
Coded table
An average in which the numbers are added and divided by the number of numbers
Arithmetic Mean
A type of average that is calculated by way of the reciprocals of numbers. Specifically, the harmonic mean is defined as the reciprocal of the arithmetic mean of the reciprocals of a specified set of numbers.
