Ordered Variable is one where you can put the data into order, bt not give it an actual number. The height of a person compared to other's height is an ordered variable.
An ordered variable is one where you can put the data into order, but not give it an actual number. The height of plants compared to each other is an ordered variable, e.g the plants growing in the woodland are taller than those on the open field.
(x,y) or (variable that cones first in the alphabet, variable that comes second in the alphabet)
Ordered variables give you more information than categoric variablesbut less information than continuous variables.An example of an ordered variable would besmall, medium or large lumps of http://wiki.answers.com/rc9-increase-surface-area.htm
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
By convention, 'x' is almost always the independent variable, but it doesn't have to be.
On whichever variable is considered the y-variable. It would be the second element of each ordered pair of data points.
Y-axis
Any ordered pair that makes the set true
the first number in an ordered pair is the x coordinate it is one of the values that the independent variable has taken on
a variable that depend on the independent variable
Independent variable is the variable that you change in an experiment.
