## Task 6: How Far Does It Jump?

04 Apr

Task 6: How Far Does It Jump?                                                   Name:

The origami from is a common and simple design.  A relevant question of interest may be ‘how far does it jump?’. For this task, you will work with your recitation members to address this question. Though there are many interesting experimental design questions relevant to this task, we will focus our efforts on analysis.

Experimental procedure:

1. Each member of the class constructs an origami frog following the instructions given.
2. Class members will work in groups to measure the distance each frog jumps. (Once each).
3. The orthogonal jump distance will be measured from the starting line to the most distance point on the frog (values may be negative).
4. Students will record and work with data for the entire class.

For the analysis:

• Summarize the data using appropriate numerical and graphical methods. Describe what you learn from these.
• Construct and interpret a 95% confidence interval for the mean jumping distance of an origami frog.
• Implement and interpret a hypothesis test to determine if the mean jumping distance is more than 6 inches.
• State and justify your conclusions.

Include relevant excerpts from your output in a brief report describing your analysis and conclusions.

The report must be typed and double-spaced; about 3-5 pages including graphics. Attach your code as an appendix (not part of the 3-5 pages).

Include the following (labeled) sections:

1. Problem Statement
2. Methods
• Conclusions
1. Discussion

1. Problem Statement: In this section, the author will describe the question(s) being addressed in the analysis and any relevant background that is helpful to understanding the question. (1-2 paragraphs)

1. Methods: In this section, the author will indicate the methods used, describe the question addressed by each method, and interpret relevant computer output.

III. Conclusions: In this section, the author will describe overall conclusions and the justification for these conclusions from the work done. In particular, how would you answer the original question posed?

1. Discussion: In this section, the author will discuss the limitations of his/her analysis did (e.g. did you have to make any particular assumptions? Was there missing information? ), describe additional questions that would be of interest to investigate with the data, and offer any final insights into the question under consideration.

Exceptional analysis and write-up             +2

Taking the analysis and report from ‘good’ to ‘excellent’ or from ‘excellent’ to ‘exceptional’ does not necessarily mean adding more (graphics, words, etc.) – though this might be part of it, rather it means conducting a more thoughtful and careful analysis and preparing a more organized and informative report on your work.
