Question
1- Cindy Ho, VP of Finance at Discrete Components, Inc. (DCI), theorizes that the discount level offered to credit customers affects the average collection period on credit sales. Accordingly, she has designed an experiment to test her theory using four sales discount rates (0%, 2%, 4%, and 6%). Cindy wants to control for the size of the customer but not to test for it as the main variable of interest so she classified DCI's credit customers into three categories by total assets (small, medium, and large). Then, she randomly assigned four customers from each category to a sales discount rate. Cindy's experimental design is a ________.
a. normalized block design
b. completely randomized design
c. factorial design
d. random block design
e. partially randomized design

In Cindy's experiment, "sales discount rate" is ________.
a. a surrogate variable

c. a blocking variable
d. a treatment variable
e. a constant
3- BigShots, Inc. is a specialty e-tailer that operates 87 catalog websites on the Internet. Kevin Conn, Sales Director, feels that the style (color scheme, graphics, fonts, etc.) of a website may affect its sales. He chooses three levels of design style (neon, old world and sophisticated) and randomly assigns six catalog websites to each design style. In Kevin's experiment "sales at a website" is _______.
a. a blocking variable
b. a concomitant variable
c. a treatment variable
d. the dependent variable
e. the independent variable
a. normalized block design

Explanation / Answer
1)
Ans - d) Random Block Design.
Explanation - As she finally assigns four customers from each category to a sales discount rate but the discount rate groups are specific, so it is a random block design.
--------------------
2)
Ans - d) A treatment variable.
Explanation - The study of average collection is mainly based on type of discount offered to customers, so its a treatment variable.
---------------------
3)
Ans - d) the dependent variable
Explanation -As sales is being monitored here based on several other independent variables, so its a dependent variable.
