Appendix C: Creating Equations in DataStudio
Step 1: Create a new equation. On the main toolbar,
click the Calculate button to open the Calculator
dialog. In the Calculator dialog, click the New button.
Step 2: Type in and/or
build the equation.
(Use the Scientific,
Statistical, and Special
menus, and the
trigonometric functions
to build the equation.)
Click the Accept button.
Step 3: Define the
dependent variables.
Under “Variables,” use
the down arrow to select
a variable or constant,
etc. and click OK.
(Example: For “T,” select
“Data Measurement.” In
the pop-up, select
“Temperature,” and click
OK. Under Variables, for
“m” and “c”, proceed to
step 4, creating the
experiment constant.)
Step 5: Label the
units. Click on the
Properties button to
open the Data
Properties dialog and
enter the name and
units. (Example: In
the Data Properties
dialog, type “specifc
heat” in the name box
and “J/g ° C ” in the
units box.)
Step 4: Enter any experiment
constants. Use the (+) button to
create an experiment constant. Click
New, then enter the name, value and
units for the constant. Click the
Accept button. Go back to the
Variables menu and select “experiment
constant” (e.g. for “m” and “c”). Click
OK.
Step 6: Save the
equation. Click
the Accept
button.
Note: Each time you build a new equation, click the New button. To edit a completed
equation, double click on the equation in the Data list, make your changes, and click the
Accept button to save your changes.
