How to Graph Using
DRY MIX
.
DRY MIX is an acronym to help you remember
how variables are plotted on a graph. It also
serves as a reminder that there are two names for
each variable. Scientists use both names.
D = dependent variable
R = responding variable
Y = graph information on the vertical axis
M = manipulated variable
I = independent variable
X = graph information on the horizontal axis
Dependent Variable or the Responding
Variable is the response to the change you make
with the independent/manipulated variable. This
variable is observed during as well as at the end of
the experiment. You do not know the resulting
response before the inquiry/experiment. It is what
you measure. It goes on the Y axis.
Examples: temperature, distance
Independent Variable or Manipulated
Variable. Some people nickname it the I-do
variable. Often it is a unit of time (minutes, hours,
days). You know this before you begin your
inquiry/experiment. It goes on the x axis.
Controlled Variables are not graphed, but these
could affect the results of the experiment. Have as
many controlled variables as possible to add
validity.
Extraneous Variables are not graphed. They are
unanticipated, unwanted events, which may cause
incorrect experimental results and wrong
conclusions.
