PROJECT
Directions: This assignment is a course-long project whereby you will work on the project in each module. You will turn in your completed project at the end of Module 8.
Create a survey question to ask others. The following are examples or some survey questions:
1. Choose a random number between 1 and 10 inclusive.
2. What month of the year does your birthday fall on? Write the numeric value from 1 to 12.
3. How many keys are in your possession at this time?
4. How many siblings do you have?
In Module 1, you will submit your survey question to your instructor for approval. Once you are notified of its approval, you may begin conducting a survey using your question.
You will need at least 25 participants and will need to keep the following record for each person:
a. Gender
b. Age
c. Date surveyed
d. Survey response
Please also keep a count, if any, non-willing participants. For example, if you chose the first survey question, then you might have the following records:
|
Participant # |
Gender |
Age |
Date Surveyed |
Survey Response |

18 |
12/10/12 |

F |

12/15/12 |

|

12/17/12 |

Please answer the following questions:
1. How would you rate your data gathering effort? Would you consider your data to be unbiased? Explain what steps you took to keep the data unbiased, or explain what could have done better to prevent the bias.
2. Before you begin analyzing the data, what do you believe you might conclude from it? This is not limited to any single question, but rather you are asked to formulate a claim based on the results.
3. Create a table and record your data from the survey. You may use the table below as a template or use Excel (note: if you decide to use Excel, please be sure to upload that file as well; remember that iBoard allows you to upload multiple files).

a. Compute the median, mode, range, mean, variance, and standard deviation of the survey response. (You may use technological tools like Excel, a TI graphing calculator, or try finding a free online tool that will help you with your computations.)
b. Compute the median, mode, range, mean, variance, and standard deviation of the survey response from only the male participants.
c. Compute the median, mode, range, mean, variance, and standard deviation of the survey response from only the female participants.
4. Construct a frequency distribution table of your results
5. What type of distribution does your data fall under? Justify your answer.
6. Do you expect to have about the same results in a larger data sample? What would you be able to infer about the general population based on your findings?
7. Make a claim based on your findings (you can claim what you inferred about the population from the previous problem) and test it by doing the following:
a. Identify the null hypothesis.
b. Identify the alternative hypothesis.
c. Identify the test statistic, P-value or critical value(s), and what test you will use to test your claim.
d. Identify the conclusion about the null hypothesis and final conclusion that addresses the original claim.
