a plot that splits each data value
into a "leaf" (usually the last
digit) and a "stem" (the other
Stem-and-Leaf Plot / digits). Stemplots are used for
Stemplot smaller sets of quantitative data.
You can easily identify outliers,
data clusters, or gaps on a
stemplot.
a visual representation of data
which compares values in
Double Bar Graph
different categories and groups
a visual representation of data
which compares frequencies of
Histogram
different numeral intervals

Ratio
more values
Proportion The relative size of elements in a design
A way to represent part-to-whole relationships, where
Percentages
the percent is the part out of 100
Numbers expressed as the product of a base-10
Scientific Notation
number and a number between 1 and 10
An easily remembered fraction that can be used to
Benchmark Fraction

Set of counting numbers starting at 1 and increasing
Natural Numbers by 1s up to infinity; sometimes called "counting
numbers". For example, 1,2,3,4,5.
Infinite set of positive and negative counting numbers
