Lab 2

1. Discuss what a linear regression is used for. Discuss the assumptions of a linear regression. Discuss how to evaluate a linear regression. (Read pages 151-155 in your text)
2. Discuss using the process flow shown in Figure 3.14 to evaluate the correct handling of projects within the model.
3. Fill in the results in Table 1 and discuss the implications to the model. Did the number of projects violate one of the assumptions? How does changing how that variable improve the model (Refer to Table 1)?
4. What recommendation about how to use projects in the model? What recommendations would you give to the organization regarding the number of projects assigned to employees (Justify by adding another table and refer to it)? Is the model accurate enough to give other recommendations? Is this a model that is for one-time use or recurring use?
