Re: Histograms – Paperclip Experiment
A HARDCOPY of this assignment is due on Thursday, November 6th at the beginning of class.
PART I: Collect Experimental Data
• Bend the provided 30 paper clips until they fail. o Follow the instructions presented in class on how to bend the paperclips.
• Record the number of bends until failure for all 30 clips • Determine the frequency of failure from 1 to 20 bends
o If the paperclip lasts more than 20 bends, note their frequency in the “20+ bends” row, and mention the frequency of this result in your paper.
• Record any additional observations about the paperclips that might be useful.
PART II: Organizing the Data Create:
1. A table and histogram (using EXCEL) from your team’s data (30 paperclips). 2. A table and histogram (using EXCEL) from the data collected from the entire class (300 paperclips). 3. A table and histogram (using EXCEL) from the data collected from all 8 sections of EGR 186 (2400 paperclips).
Be sure your graphs are appropriately scaled. i.e., don't compare the # of bends of a group (30 paperclips) to the entire class (300 paperclips). If you want to compare 30 paperclips to 300, convert to %.
PART III: Presenting the Experiment Write a report to explain the experiment, show the data collected, and discuss the results.
1. Include a cover page with appropriate information. 2. The report must contain a 1) problem statement, 2) methods section, 3) results section, and 4) conclusion (make
a conclusion by writing a short paragraph to answer the provided questions). a. Conclusion: discuss your observations regarding the frequencies of paperclip failure.
i. Is there a distinct trend or trends? ii. Discuss why such a result may have occurred (re-‐examine the paperclips for any possible clues
to the trends observed).

PAPER FORMAT NOTES: • Write your paper in 3RD PERSON! i.e “The data show…”, NOT “I saw a trend in the data…”. In engineering
technical papers, the data is the focus (not you…). • Properly label title and axes of every graph. No legend is required. • Explain what each graph and table is in the text. Refer to each graph in the text (Figure 1, Figure 2, Table 1, etc.). • Each graph must also have a caption centered directly BELOW the figure (i.e. Figure 1: Team results of…). • Each table must have a caption centered directly ABOVE the table (i.e. Table 1: Team results of…). • Refer to the journal articles you read for the Tech Comm Project for format, header, figure, table, and caption
examples.
