Descriptive statistics

quantitatively describes or summarizes features of a collection of information.




Inferential Statistics

infers properties of a population.




Nominal

a measurement with values which have no numerical value, such as gender or occupation.




Ordinal

, One value, despite not having a numerical classification has significantly "More value" that the
previous value. [For example: Elementary Education, Middle school education, High school
education....Differences of 4 years of educational background.]




Interval

the distance between attributes does have meaning. For example, when we measure
temperature (in Fahrenheit), the distance from 30-40 is same as distance from 70-80. The
interval between values is interpret-able.




Ratio

is defined as a quantitative data, having the same properties as interval data, with an equal and
definitive ratio between each data and absolute "zero." [Example: Height]




Levels of Measurement

nominal, ordinal, interval, ratio.




Numeric

something to do with numbers.




Discrete

take on an infinite value.
