Re: Statistics: Definition of Terms

Quantitative data: Data which
are measurable or quantifiable,
such as length, weight, etc.

Qualitative data: Data which
measure intangible or objective
data, such as peoples'
attitudes and opinions.

Discrete variable: a variable
with a limited number of values
(eg, gender (male/female),
college class (freshman/
sophomore/junior/senior).

Continuous variable: A variable
that can be expressed by a
large (sometimes infinite)
number of score values. For
example, height, temperature,
and grade point average are
continuous variables.

Dichotomous: A dichotomy is any
splitting of a whole into
exactly two non-overlapping parts.
(eg. True/False  Under 40/40+)

Trichotomous: Dividing into 3 parts.
(eg. Paper/Rock/Scissors)

Multinomous: ??Multiple parts??
(eg. Hydrogen/Helium/Lithium/Berylium/Boron/Carbon...)

Nominal, Ordinal, etc. :

Primary Source: An original source,
such as someone's diary or journal,
a survey or interview, letters,
autobiographies, and observations.

Secondary Source: Any material, other
than the original document, used in
the preparation of a written work.
Secondary sources include criticisms,
reviews, or other resources based on
a primary source.
