Histograms-Paperclip Experiment.
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 us
eful.
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) f
rom 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 paperclip
s 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) me
thods 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 trend
s?
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 3
RD 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 th
e journal articles you read for the Tech Comm Project for format, header, figure, table, and caption
examples.
