Adding a Trendline The primary reason for graphing data is to examine the relationship between the two variables plotted on the X- and Y-axes.

Note: Error bars may not be visible if they are smaller than the size of the data marker. Then enter the uncertainty for the y-values in the box marked 'Fixed Value.' You can add ' X Error Bars' in a similar manner. Choose 'Both' under 'Display' and 'Fixed Value' under 'Error Amount'. It is recommended that you change the background area to white by double-clicking on a blank portion of the graph plot area, and then select 'None' under 'Area.' Adding Error Bars Right-click on a data point and choose 'Format Data Series.' Click on the ' Y Error Bars' tab. Try changing the color of the plot area, the numbers on the axes and the appearance of the data points. You can also right-click on a feature to get a menu. Most graph features can be modified by double-clicking on the feature you want to change.

The size can be adjusted by dragging one corner. You can move your graph by clicking near its center and dragging. Choose 'As object in' to store the graph in the same worksheet as the data and click 'Finish.'

Step 4: This screen selects where you will store the graph.

Make sure your final graph has a descriptive title, axes that are labeled (with units), and no legend. Experiment with the settings to see what they do.

Step 3: This screen has multiple menus.

Since you did this before starting the Chart Wizard, just click 'Next.'

Step 2: This screen allows you to choose which data to plot.

Step 1: Choose 'XY (Scatter)' with no lines, and click 'Next.'.

(To do this, click on 'File' and choose the 'Save As' option.) You will be creating a graph of this data, similar to the one shown below. Save the file to a disk or to your personal file space on the campus network. Enter the sample data and column headings shown below into cells A1 through B6.

To begin, open Excel from the 'Start' menu on your PC (Start > Programs > Microsoft Excel). The techniques presented here can be used to analyze practically any set of data you will encounter in your introductory physics lab. Using Excel for Data Analysis Getting Started This tutorial will lead you through the steps to create a graph and perform linear regression analysis using an Excel spreadsheet. Consult your TA if you have specific questions about analyzing your data using Excel. Instructions for using the FitHaven templates are provided with the software, and therefore will not be discussed here.

A special license agreement has been obtained from the publisher for UNC-CH physics students to use these templates, which can be downloaded free of charge from the introductory physics lab website. If you decide to use Excel, you may use the FitHaven templates that accompany the Data Analysis book by William Lichten (this book can be purchased in the campus bookstore, but is not required for this lab). No matter which program you use, the section titled Determining the Uncertainty in Slope and Y-intercept on page 3 of this section may be useful to you.

You may use whichever software program you prefer, but it is your responsibility to ensure that the computational results are correct and consistent with the requirements stated in this lab manual. A third software option is PASCO's DataStudio, which is used in the introductory chemistry lab courses and should be available across campus. Instructions for using KaleidaGraph can be found on the lab website (see below). KaleidaGraph is available on the computers in the lab rooms (for your use during lab), in Phillips 245, and in the student computer labs throughout campus (in the physics folder). Another graphical analysis program called KaleidaGraph is also available, but with limited access (there is not a campus-wide site license for this program). A brief tutorial on using Excel for data analysis is included in this lab manual. Since Microsoft Excel is widely available on all CCI laptops and in ATN computer labs, you are encouraged to use this spreadsheet program to analyze your data. Data Analysis for Physics Labs You have a number of software options for analyzing your lab data and generating graphs with the help of a computer.
