Raw Data:
You will needed to run at least three trials for each paper towel.
Collect and document data in a chart. You can create a data chart on paper and add image or draw one directly in the background.
Processed data. Graph your data. You can create a graph on paper and add image or draw one directly in the background. Make sure you use the correct type of graph.
