TRUE/FALSE - Write 'T' if the statement is true and 'F' if the statement is false.
1) We want to evaluate dog owners' reactions to a new dog food product formulation that contains more vegetables.
An experiment is conducted where five stores are chosen in each of two regions (A and B) with similar sales for the original formulation. In region A, the shelves are stocked with both formulations. In region B, the stores are stocked with only the original formulation. The package of the new formula is exactly the same as the original formula except for three modifications: the color is changed (from blue to green), the content label is changed, and a yellow banner with black letters "More vegetables!" diagonally crosses the upper left corner of the bag. For a sixmonth period before and after the new product formula introduction, sales of the original version are recorded in all ten stores; for the six months after the new product formulation, sales of the more-vegetable formula in the five stores are recorded.
It would have been appropriate for this dog food test market design to have used a quota matrix in selecting participating stores.

For a sixmonth period before and after the new product formula introduction, sales of the original version are recorded in all ten stores; for the six months after the new product formulation, sales of the more-vegetable formula in the five stores are recorded.
In the dog food test market, the decision to use two regions from which to draw the 10 stores involved in the test describes which task of conducting an experiment?
A) Select relevant variables
B) Specify treatment levels
C) Choose experimental design
D) Select and assign cases
E) Pilot test, revise, and pretest
79) We want to evaluate dog owners' reactions to a new dog food product formulation that contains more vegetables.
An experiment is conducted where five stores are chosen in each of two regions (A and B) with similar sales for the original formulation. In region A, the shelves are stocked with both formulations. In region B, the stores are stocked with only the original formulation. The package of the new formula is exactly the same as the original formula except for three modifications: the color is changed (from blue to green), the content label is changed, and a yellow banner with black letters "More vegetables!" diagonally crosses the upper left corner of the bag. For a sixmonth period before and after the new product formula introduction, sales of the original version are recorded in all ten stores; for the six months after the new product formulation, sales of the more-vegetable formula in the five stores are recorded.

82) We want to evaluate dog owners' reactions to a new dog food product formulation that contains more vegetables.
A promotional booth is set up at 10 dog events around the country. We distribute a one-day sample of the new more-vegetable formula to dog owners who come by the booth. If dog owners also provide their e-mail, they will be emailed a 20% off coupon for their first purchase. We measure the effectiveness of the more-vegetable formula by the number of coupons that are used to make purchases in stores.
This is an example of ________.
A) static group comparison design
B) after-only design
C) posttest-only control group design
D) random assignment
E) pilot testing

84) Which of the following is not true about the three dog food reformulation experimental designs: (1) based on dog responses, (2) based on sales in stores, and (3) based on stopping for a sample at a dog event and later using a coupon in a store.
A) Design 1 will reveal the dog's reaction, but this may not translate to product sales in stores.
B) Design 2 will reveal that the dog owner has a positive disposition about feeding their dog vegetables that translates to initial sales, but that may not translate to repeat sales if the dog does not eat the food.
C) Design 3 will reveal that the dog reacted favorably to the formula and the dog-owner has a positive disposition about feeding their dog vegetables if the coupon is used to make a purchase in the store, but that may not translate into repeat sales due to a higher subsequent price.

89) First, there must be an agreement between independent and dependent variables. The presence or absence of one must be associated with the presence or absence of the other. The conclusion is based on whether more theft reports occur from lone observers or from paired observers. Second, the time order of occurrence must be considered. The effect must not precede the manipulation. This does not apply in this example because people would not report a crime before observing it occur. Third, researchers must be confident that other extraneous variables did not influence the dependent variable. To do this, researchers control these possible extraneous variables by standardizing the environment in which the experiment takes place. In this example, the store was really a controlled lab with confederates acting as the thief and accosted shopper.
90) The steps in conducting an experiment are as follows: (1) select relevant variables, (2) specify the level(s) of the treatment, (3) control the experimental environment, (4) choose the experimental design, (5) select and assign the participants, (6) pilot-test, revise, and test, and (7) analyze the data.
91) There are several threats to internal validity. Any weakness in the design that may cause an outcome that would otherwise be attributed to the experimental treatment is a threat to internal validity. Common threats include: history, maturation, testing, instrumentation, selection, statistical regression, experimental mortality, diffusion of treatment, compensatory equalization, compensatory rivalry, resentful demoralization, and local history.
92) Preexperiments are designated as such because of their weak designs. Preexperiments do not provide for the random assignment of participants. Some of the designs also do not allow for the use of a pretest that can be used to ensure equivalence between the control and experimental groups. Further, some preexperiments do not use control groups. True experiments are the strongest at minimizing the threats to internal validity. This is accomplished primarily through random assignment, but control groups are also used in most true designs. Pretesting is also a possible method for ensuring equivalence between groups. Quasi-experimental designs are weaker in terms of internal validity but strongest for external validity. This is because quasi-designs use field settings that maximize the generalizability of the results.
93) An asymmetrical relationship exists when a change in one variable (independent variable) is responsible for a change in another variable (dependent variable). There are four types of asymmetrical relationships. A stimulus-response type occurs when an event or change results in a response from some object. A property-disposition type occurs when an existing property causes a disposition. A disposition-behavior type of relationship occurs when a disposition or attitude causes a specific behavior. A property-behavior type of relationship occurs when an existing characteristic such as age causes a specific behavior.
94) The three types of evidence are (1) covariation between the two variables, (2) time order of events moving in the hypothesized direction, and (3) the elimination of other possible causes of the outcome. Covariation asks if the variables occur together in the way hypothesized. Time order of events asks whether the independent variable occurs prior to the dependent variable. Elimination of other causes asks if there are other explanations for the outcome.
