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.
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
(x,y) or (variable that cones first in the alphabet, variable that comes second in the alphabet)
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
In the ordered pair (20, 140), the first value, 20, typically represents the independent variable or the input of a function, while the second value, 140, represents the dependent variable or the output. In a specific context, such as a graph or data set, these values could signify measurements, such as time and distance, or any other two correlated variables. The exact meaning depends on the context in which the ordered pair is used.
To find ordered pairs of an equation, you can choose a value for one variable and then solve for the other variable. For example, if you have the equation (y = 2x + 3), you might choose (x = 1), which gives (y = 5). This results in the ordered pair (1, 5). Repeat this process with different values of (x) or (y) to generate more ordered pairs.
