Creating Graphs Using Excel
You are encouraged to use Excel to create the graphs required for the labs 4 and 8 assignments. The ability to create graphs is a useful skill to have!
All UMGC students have access to Excel. See this page for information: https://www.umgc.edu/help/help-article-base.html?k…
Resources:
There are many good Excel Tutorials online, especially on YouTube, that you can use if you need help creating graphs.
Here is one suggestion (may be slightly different depending on the version used – you can stop at minute 4:30 – equation for trend line not needed): How to make a scientific graph in Excel

A Few Tips:
Scatter plots or bar graphs work well for the data you need to plot in labs 4 and 8.
Before you start, think about how you want the graph to look. Make sure your graph provides enough information so that the reader can understand the data presented just by looking at the graph.
The independent variable should always be on the x-axis and the dependent variable should always be on the y-axis.
Label the x and y axis, include the units of measure.
Include a descriptive title for your graph.
The originality of your lab assignment will be checked with Turnitin. Please review the originality report, and if needed, submit a revised assignment before the submission deadline.
