DESIGNING YOUR SAMPLING SURVEY & WRITING THE PROPOSAL:

Write four narrowly focused questions that fit within the theme of your senior project.  Two must involve quantitative variables, and two must involve categorical variables.  Mr. Nelson will meet with the leaders to discuss the group's proposed questions.  

Once Mr. Nelson has approved your questions, students will begin preparing FOUR DOCUMENTS (the proposal, survey questionnaire, response sheet, and promotional flyer).  

Leaders will assign roles to each student.  BEFORE starting their tasks, students should review the relevant Survey Design Tutorial, and check out some survey documents from previous studies.  The template below will guide the groups through the many decisions required to conduct a sampling survey that lacks bias, and maintains the three Inference Conditions (Random Sample, Normal Sampling Distribution, and Independence).

IMPLEMENTING YOUR SAMPLING SURVEY:

All students will implement the sampling survey.  Teams of two usually work best, but this decision will be up to the leaders and the group at large.  Once the data has been collected, the teams will input the data into Excel.


ANALYZING THE DATA & PREPARING A REPORT

All team members will participate in writing the report.   Each member will provide one of the following: four-step inference test of significance; a display showing a graphic representation of the sampling distribution and P-value; OR a confidence interval estimating a mean or proportion.  Leaders will receive further instructions on the layout of the report, and will be shown examples to follow.
