Question 1

Evidence of concomitant variation, time order of occurrence of variables, and elimination of other possible causal factors, when combined, demonstrate conclusively that a causal relationship exists.

Accepted Answer

While evidence of concomitant variation, time order of occurrence of variables, and elimination of other possible causal factors strongly suggest a causal relationship, they do not conclusively demonstrate it due to the potential for unobserved variables or complexities in the system.

Question 2

Also known as the after- only design, the one- shot case study may be symbolically represented as: X O₁.

Accepted Answer

The symbol X represents the exposure or intervention, OS1 stands for observation after the intervention, U1 represents the comparison or control group, B11 indicates the measurement of the outcome before the intervention, S1 represents the measurement of the outcome after the intervention, and U1B0 indicates the absence of the intervention in the comparison or control group.

Question 3

The static group is a two- group experimental design. One group, called the , is exposed to the treatment, and the other, called the , is not. Measurements on both groups are made only after the treatment, and test units are not assigned at random.

Accepted Answer

The correct terms for the two groups in a static group experimental design are experimental group (EG) and control group (CG). In this design, the EG is exposed to the treatment while the CG is not. Measurements are taken on both groups after the treatment has been administered, and test units are not randomly assigned. Choice A, random group (RG), is not a recognized term for a group in a static group design. Choice B, pretest group (PG), is not applicable in a static group design where measurements are only taken after the treatment, not before. Choice C, control group (CG) and pretest group (PG), is incorrect because there is no pretest group in a static group design.

Question 4

The conditions that must be satisfied before making causal inferences include all of the following except .

Accepted Answer

The role of evidence is not a specific condition for causal inference. The key conditions are elimination of other possible factors, concomitant variation, and time order of occurrence of variables.

Question 5

Which of the following statements is a limitation of Latin square designs?

Accepted Answer

Latin square designs do not allow the researcher to examine interactions of the external variables with each other or with the independent variable (limitation A), and they require an equal number of rows, columns, and treatment levels, which can sometimes be difficult to achieve (limitation B). Therefore, option D is correct as it includes both limitations. Limitation C is not accurate as Latin square designs can control for multiple external variables, but only one at a time.

Question 6

refers to an extraneous variable attributable to the loss of test units while the experiment is in progress.

Accepted Answer

Mortality refers to the loss of participants or test units during the course of an experiment, which can affect the results and validity of the study.

Question 7

A _ is a quasi- test market in which respondents are pre- selected, then interviewed and observed on their purchases and attitudes toward the product.

Accepted Answer

A simulated test market is a quasi-test market in which respondents are pre-selected, then interviewed and observed on their purchases and attitudes toward the product.

Question 8

Which statement is not true about simulated test markets?

Accepted Answer

Simulated test markets are designed to avoid the issues mentioned in A and B, as they are conducted in a controlled environment to prevent competitors from interfering and to speed up the process, reducing the risk of competitors beating the firm to market.

Question 9

Which of the following is true of the one- shot case study preexperimental design (X O₁)?

Accepted Answer

The one-shot case study design lacks a control group, so it doesn't allow for comparison when X is absent (A), and it doesn't involve random assignment of test units (B).

Question 10

refers to an extraneous variable attributable to changes in the test units themselves that occur with the passage of time.

Accepted Answer

Maturation is an extraneous variable that refers to changes that occur within the test units themselves with the passage of time. This is particularly relevant in longitudinal studies where the same participants are tested over time, and where any changes that occur over time may have an impact on the results of the study. Examples of maturation effects might include changes in physical development, cognitive abilities, or emotional regulation that occur naturally over time.

Question 11

If the experimental design called for the respondents to be randomly assigned to one of three experimental groups and for one of three versions of a test commercial to be randomly administered to each group, this design would be using .

Accepted Answer

The design described in the scenario is using randomization, as the respondents are being randomly assigned to the experimental groups and to one of three versions of the test commercial. Randomization helps to ensure that any differences observed between the groups are not due to preexisting differences between the individuals in the groups, but rather are due to the experimental treatment or intervention. Matching involves selecting individuals who are similar on certain characteristics before they are assigned to groups, while statistical control and design control involve manipulating or measuring variables in order to control for their effects on the outcome of interest.

Question 12

Using the set of symbols commonly used in marketing research to denote experimental designs, which symbol below represents the process of observation or measurement of the dependent variable on the test units or group of units?

Accepted Answer

The symbol "O" represents the observation or measurement of the dependent variable on the test units or group of units. The symbol "T" represents the control group, "R" represents random assignment, and "X" represents the manipulation of the independent variable.

Question 13

The one- group pretest- posttest design may be symbolized as O₁X₂O_2.In this design, a group of test units is measured _.

Accepted Answer

In the one-group pretest-posttest design, the group is measured twice: once before the treatment (O1) and once after the treatment (O2).

Question 14

refers to an extraneous variable attributable to the improper assignment of test units to treatment conditions.

Accepted Answer

Selection bias occurs when test units are not properly assigned to treatment conditions, leading to the introduction of an extraneous variable. Instrumentation refers to changes in measurement instruments or procedures that occur during the course of an experiment, while statistical regression refers to the tendency of extreme scores to regress towards the mean in subsequent measurement. None of these choices accurately describe the situation described in the question.

Question 15

The effectiveness of a test commercial (X) may be examined by broadcasting the commercial a predetermined number of times and examining the data from a preexisting test panel. Although the marketer can control the scheduling of the test commercial, it is uncertain when or whether the panel members are exposed to it. The panel members' purchases before, during, and after the campaign are examined to determine whether the test commercial has a short- term effect, a long- term effect, or no effect. A design was used in this research project.

Accepted Answer

The answer of The effectiveness of a test commercial (X)...

Question 16

Which of the following statements is true when considering experimental versus non- experimental designs?

Accepted Answer

All the statements accurately describe the differences between experimental and non-experimental (descriptive) research designs.

Question 17

A design to measure the effectiveness of a test commercial for Sears would be implemented as follows. Respondents are recruited to central theater locations in different test cities. At the central location, respondents are first administered a personal interview to measure, among other things, attitudes toward the store (O₁). Then they watch a TV program, the respondents are again administered a personal interview to measure attitudes towards the store (O₂). The effectiveness of the test commercial is measured as O₂- O₁.

Accepted Answer

The design described involves measuring the same group of respondents before and after exposure to the commercial, which aligns with a one-group pretest-posttest design.

Question 18

A _ is a test marketing program conducted by an outside research company in field experimentation. The research company guarantees distribution of the product in retail outlets that represent a pre- determined percentage of the market.

Accepted Answer

A controlled test market is conducted by an outside research company that ensures the product is distributed in selected retail outlets, representing a specific market percentage.

Question 19

Which statement is not true concerning a standard test market?

Accepted Answer

The answer of Which statement is not true concerning a...

Question 20

is a statistical design that allows for the statistical control of two non- interacting external variables in addition to the manipulation of the independent variable.

Accepted Answer

The Latin square design is a statistical design that controls for two non-interacting external variables by arranging treatments in a square grid, allowing for the control of row and column effects in addition to the manipulation of the independent variable.
