# Unit 5 | Statistics homework help

This Discussion is based on the article, “Manager’s Guide to Forecasting” by David Georgoff and Robert Murdick from Harvard Business Review. Make sure to acquire this article before starting the Discussion.

Georgoff, D. M., & Murdick, R. G. (1986). Manager’s guide to forecasting. Harvard Business Review, 64(1), 110–120.

In this course, you will touch on a few forecasting methods, although there are many more approaches available to those managers who wish to do more. This week’s article provides an overview of many forecasting methodologies and provides a framework through which you can explore their differences.

Your objective in this Discussion is to learn to analyze a specific forecasting situation and identify the best suited methodology. You will complete three steps.

Step 1: Describe a specific forecasting need in your organization.

Step 2: Use the provided table below to analyze the requirements of the forecasting problem.

Step 3: Identify the best matching forecasting methodology to your situation and describe how it would be executed.

In Step 2, the analysis will be based on the table shown on pages 4 and 5 of the article. This table lists several questions about the nature of the forecasting situation, such as the urgency, detail required, and costs factors, and provides an overview of how well various forecasting methodologies will fit those requirements. For example, some forecasting methods cost more than others and depending on your financial resources, some of them may not be suitable. The same holds true with the math skills available or the need for high accuracy. So, understand what each category is referring to, fill in the information, and follow the table to see which methodology is recommended for your specific case. You are learning how to analyze your situation so as to pick the best approach. Please note that these 2 pages in the article (pages 4–5) go side by side. You may wish to print them out and place them next to each other to read across the rows comfortably. The table shown below is based on the table in the article.

Use this format for your Unit 5 Discussion.
