Explain whether you have homogeneity of variance, and explain how you know. Explain why it is important to know if you have homogeneity of variance.

Application: Computing t Tests
The one-sample t test discussed in Chapter 6 requires that you know the population mean. It is unusual to have this information, so most studies compare two samples instead. Each sample measures a different condition of the independent variable.
Before conducting a study, it is important to know if you would need to conduct a matched-samples t test or an independent-samples t test. Independent samples consist of two groups of different people. One group has been randomly selected and is not specifically tied to who is in the other group. Matched samples are groups that are deliberately selected to be similar to each other (matched pairs) or they are the same people in both groups (repeated measures). For example, you might want to select two groups that have similar heights. If height could affect the experiment, it could be best to match the groups on that variable. This Assignment will allow you to convey your understanding of the basic concepts related to t testing and will allow you to practice setting up and conducting an inferential parametric test in SPSS.
Scenario:
Imagine you are a researcher who believes that a relaxation technique involving visualization will help people with mild insomnia fall asleep faster. You randomly select a sample of 20 participants from a population of mild insomnia patients and randomly assign 10 to receive visualization therapy. The other 10 participants receive no treatment.
You then measure how long (in minutes) it takes participants to fall asleep. Your data are below. The numbers represent the number of minutes each participant took to fall asleep.

Explain whether you chose to use an independent-samples t test or a matched-samples t test. Provide a rationale for your choice.

Continuing with your Week 2 Project now your CEO after
reviewing your earlier Week 2 PowerPoint submission has asked your
team to complete an additional benchmark analysis task before the
upcoming Board Meeting. For this part of the project your team
needs to do an analysis of the market and operational
characteristics of your company and its financial profile. For this
project your team will need to select four companies that are
direct competitors of your company. This sample selection should be
based on revenue profitability market capitalization market
segment and product characteristics.
This project is an additional benchmark data analytics project.
The objective of this part of the project will be to do a
comparative financial analysis of your company with the averages of
the sample of four companies that will form your comparative
group.
The project deliverables will be another PowerPoint presentation
to the CEO explaining the financial performance of your company
compared to the sample of four comparable companies. The analysis
should include the following deliverables:
1. An explanation of the logic of the selection of the four
comparable group companies. Why were these companies selected?
2.Your teams data extraction strategy process and
methodology.
3. A financial comparison of your company to the average of the
comparator group on the following financial factors.
a. Profitability b. Debt Management c. Liquidity d. Asset
Management e. Value Creation based on a the 3-year trend in Free
Cash Flow
In order to complete this project your team has to select which
ratios you are going to use in each of the five categories given
above. In addition to that your team will have to briefly explain
why you are selecting the ratios you are using in your benchmark
study.
Then your team will have to collect the financial data for your
company and the financial data of the four competitor companies.
The data can be collected from two financial data bases such as
Yahoo Finance Lexis Nexis Plunkett or bizstats.com. Your team
will then have to collect and calculate the averages of the four
competitor companies. (Please note that no ratio calculations are
required for each company the ratios should be readily available
on the websites noted above. You will only need to calculate the
average ratios for the four companies combined.)
Your team will proceed to developing a PowerPoint presentation
presenting the comparison and your teams commentary of what your
team discerns from the comparison. PowerPoint should not have more
than ten slides. Just like the previous project your team should
use Webex or Voicethread and prepare an oral presentation that
presents your PowerPoint presentation. Each team member must
participate in this presentation.
