**Directions for importing data into the graphing calculator (TI-84
Silver Plus)**

These directions will lead you step by step from importing the data into
the TI Connect™ software (PC version), to transferring data to the
calculator, and graphing the data.

A.  [Before importing the data:]{.underline}

1.  Import the file *Ozone_profiles.txt* into MS Excel, note the number
    of columns.

2.  Depending on what type of operating system your computer has:

3.  Click TI Data Editor (PC version)

-   List is the default data entry structure. Create a new variable in
    TI Data Editor for each column in MS Excel (icon is a sheet of
    paper) e.g. 2 columns in Excel = 2 variables in TI Data Editor.

-   Highlight the first cell of the first column of the SAGE III data
    that contains only numerical data, right mouse click, select
    *Properties*, and choose a variable name. For simplicity's sake
    choose L1. Repeat the above steps for the next column, naming that
    column L2.

-   Click Actions  Send All Lists

4.  Connect the calculator to the computer via the TI Connectivity USB
    Cable. Note: The USB portion of the cord attaches to the computer's
    USB, while the smaller end attaches to the I/O port on the
    calculator. A pop-up screen **Select TI Device** will appear, after
    the search is complete, make sure that the name of your calculator
    is highlighted and press *Select*.

C. [Graphing the SAGE III data on the Calculator:]{.underline}

1.  Check that the data transferred correctly:

-   Brings up the List menu

-   Press 1 -- to select L1

-   Shows the first couple of entries for L1

> ![](media/image5.png){width="1.2805555555555554in"
> height="0.7701388888888889in"}

-   Repeat this check for L2

2.  Define the parameters for the graph:

-   Brings up STAT PLOT Menu

-   Selects Plot1

```{=html}
<!-- -->
```
-   Turns Plot1 on

> ![](media/image6.png){width="1.2798611111111111in"
> height="0.8534722222222222in"}

-   Type: scatter plot is the default, change nothing

3.  Graph the data:

-   Selects ZoomStat  SAGE III graph only

> height="0.9097222222222222in"}

D. [Graphing the ozonesonde data:]{.underline}

1.  In step B. 3, highlight the ozonesonde data this time. Name each
    column L1 and L2. Follow the instructions as stated. If the TI
    Connect ™ program is not closed and the calculator is not
    disconnected from the cable, then B. 4 will not occur. However, if
    either of these happens then B. 4 will occur as stated.

2.  The screen below will appear. When it does, click *Replace All*.
