In excel, enter your data. Column A will be the horizontal (x) axis and column B will be the vertical (y) axis. Highlight both columns and click the chart wizard button. It is on a toolbar near the top of the screen, and looks like a little bar graph. When the chart wizard window comes up, pick chart type XY (scatter), than click ‘next’. At the next window (Chart Wizard 2 of 4), click ‘next.’ At Chart wizard step 3 of 4, you can label the axes of your graph.

Unformatted text preview: You will be given several options for the type of trendline you want to fit to your data. The spectroscopy lab (fall semester) and Hubble Red Shift lab (spring semester) both use a linear best fit line. Next go to the tab labeled ‘options’. Click on ‘display equation’ and ‘display R-squared value’. The R-Squared option is a measure of how well the data points fit the trendline. R 2 = 1 is a perfect fit. If you know that the graph should pass through a certain point on the vertical axis, than you can set the trendline to pass through that point as well by checking ‘set intercept =’ (and whatever value the graph should have at x = 0).
