Using Excel - A Trendy Day in the Lab
Part A: Making a Scatter Plot
1. Open Excel.
2. Open the file called “Day 3 - Tree Data.xls”
3. Highlight the data. (Not the titles.)
4. Click on the “Insert” tab.
5. Create a scatterplot of the data by clicking on the “Scatter with only Markers” button in the
“Scatter” group.
6. Click on the “Layout” tab and add appropriate labels and a title.
7. Right click on the x axis and format the axis so that the major unit is fixed at 1.0.
Repeat for the y axis.
8. Select the data points by right clicking on one and add a linear trend line.
9. Check the boxes to display the equation and the R2 value on the graph.
10. Extend the trend line (“forcast” forward/backward under options) to predict the height of a 15
year old tree (HINT: need to look at the range of the ages already to determine how far to
extend the line).
11. In a different cell predict the height of a 15 year old tree using the equation from your
calculated trend line.
12. Right click on graph and select Move Chart, select the option for new sheet.
13. Print off the graph and your answers and hand it in.
