OBTAINING THE DATA FOR THE RESEARCH CONTEXT
Assignment Overview
In this Case Assignment, you will be reading several articles and sources about sampling, about participant recruitment and interaction, and about managing the relationship between research participants and researchers. You will then be asked to think about how these issues apply to your project and your research questions, and to develop an appropriate sampling plan for your study taking all these issues into consideration.
As the course progresses, you will be making a series of decisions in which you will increasingly specify the structure of your project. These decisions build on each other in critical ways. However, you are not locked into previous decisions if you subsequently decide you need to change direction. As before, you have an opportunity to go back and revise and/or extend the previous sections completed in previous modules. If you do revise earlier sections, please include them and indicate what changes you have made to them.
Case AssignmentPrepare a 5- to 7-page paper in accordance with the following Assignment Expectations, describing the sampling issues for your project, in accordance with the following outline:
Identify the organization within which you are going to be constructing your project, and the nature of the problem that you are investigating.
Identify the general kinds of respondents within the organization, and the kinds of information that you will need to collect from each group of people in order to complete your project.
Complete the following grid describing the respondents in your project and some things about them:
Interview(s)
Subject Role Topics When Purpose IRB concerns?
Questionnaire(s)
To whom Role(s) Topics Purpose IRB concerns?
Identify any additional issues which you think might arise in terms of obtaining cooperation from your respondents or that might complicate getting the information that you need.

Module 3 SLP
OBTAINING THE DATA FOR THE RESEARCH CONTEXT
Descriptive statistics are used to learn about the characteristics of a measure that is collected over time or may be a measure of an item from a survey administered to many people. Typically, descriptive statistics are the average score (mean), the maximum, the minimum in the scores along with the variation. Descriptive statistics is used to describe the measures rather than to make inference centered around the same item or conceptual construct being measured. Thus, descriptive statistics is not inferential statistics and does not use probability to infer behaviors of a population from which the measures were drawn.
Descriptive statistics fits the background analysis for your firm selected for your DSP. Here you have financial and performance measures of the firm with respect to others in the same competitive space. In most cases descriptive measures can be used to generate trend lines to try and forecast based on past measures.
Here is a descriptive spreadsheet for the United Way of Orange County that shows the average and standard deviation for revenues and expenses from the 990 Report we looked at in SLP 2. Here in this spreadsheet Figure 4 (click the image to open the file) you see by clicking the various tabs on the lower part of the spreadsheet graphs that can be generated from this 990 data. Columns F and G have the average and standard deviation of the revenue and expense measures, but they are rather static. To use the years of revenue and expense measures, you can click the Forecast Sheet tab on your tool bar. This is how the graphs for Revenues, Expenses, and Net were produced where a technique called exponential smoothly is used that factors in the four years of data to produce the trend lines in the forecast.

SLP Assignment Expectations
Now examine the secondary data you have on your firm from SLP 2 or add more to the data as needed. Look at the sample and review the Excel book and particularly the one on Exponential Smoothing. Calculate some descriptive statistics for your data and prepare some forecast charts. Remember the Forecast Sheet tool on the upper toolbar next to What If Analysis. Produce a spreadsheet with associated graphs; also provide a page or two to discuss this data analysis and the conclusions you have drawn. Add this to the growing work you have on the Background for the firm you are studying.
