SCENARIO 14-11 A weight-loss clinic wants to use regression analysis to build a model for weight loss of a client (measured in pounds).Two variables thought to affect weight loss are client's length of time on the weight-loss program and time of session.These variables are described below: Y Weight loss (in pounds) Length of time in weight-loss program (in months) 1 if morning session, 0 if not Data for 25 clients on a weight-loss program at the clinic were collected and used to fit the interaction model: Y Output from Microsoft Excel follows:
-Referring to Scenario 14-11, what is the experimental unit for this analysis?
A)A clinic
B)A client on a weight-loss program
C)A month
D)A morning, afternoon, or evening session

Quizplus · Accepted Answer

The experimental unit in this analysis is a client on a weight-loss program, as the study is focused on the variables affecting individual weight loss. The experimental unit for this analysis is a client on a weight-loss program, as the goal is to analyze the factors that affect weight loss for individual clients.
