HW12: Histograms – Button Experiment

PART I: Collect Experimental Data

PART II: Organizing the Data


You will have 1 table and 3 histograms. Be sure your graphs are appropriately scaled. In other words, do not compare the diameters of your group (30 buttons) to the entire section (300 buttons). If you want to compare 30 buttons to 300, convert to a percentage (%).

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).


  1. Conclusion: discuss your observations regarding the frequencies of button diameters.
  2. Is there a distinct trend or trends? Is/Are the trend(s) similar across all 3 histograms?
  3. Discuss why such a result may have occurred.


Write your paper in 3RD PERSON! For example, “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 articles you read for the Tech Comm Project for format, header, figure, table, and caption examples.
