Statistical Analysis Project PMU 2014

This document outlines a semester-long project for a Statistical Analysis course at Prince Mohammad Bin Fahd University. The project, worth 15% of the final grade, requires students to form groups and conduct business research using statistical methods. The project involves selecting a business area, creating a questionnaire with various types of variables, choosing a sampling method, applying statistical analysis techniques, and submitting a final report. The analysis includes descriptive statistics, measures of center and dispersion, relationship between variables, estimation, hypothesis testing, and regression analysis. The project aims to assess students' understanding of statistical concepts and their ability to apply them in a business context.

Project Assignment Spring Semester -- 2014
[This semester long project will count towards 15% of your final course grade. It aims to test your general
understanding of the course and your ability to use Statistics in business research. Please read the attached
instructions carefully and following the general guidelines provided. Submit the required assignments on time
and try to produce a research as professional as possible.]
Form a group of 3-4 members (maximum group size is 4.) Decision about the group members once
made should not be changed.
Perform the following tasks sequentially and note the due dates.
Group Assignment
1. Thinks of a business area with which you feel comfortable and able to do the research in.
Think of an objective you want to prove (or disprove). Narrow down your ideas to a specific idea
after discussing your ideas in the classroom and getting input from fellow students.
Due Date: 04/03/2008
2. Write a questionnaire that you feel will help you test the accuracy of your ideas. Make sure
that those questions in the questionnaire measures rather than questions that ask. In other words,
use “how” and “why” rather than “what” questions.
Make sure that this questionnaire has at least:
- 2 NOMINAL variables
- 2 ORDINAL variables
- 2 DISCRETE variables
- and 2 CONTINUOUS variables
3. Choose a method to select your sample. You will have to discuss this method in class or in the
office hours.
Due Date: Will be announced in class
