Reasons for researchers regressing to unethical behaviour31

For reasons of time, convenience and cost, online channels have become the dominant in many areas of marketing research. It has been recognised for some time that the research community needs a coherent ethical code of practice to guide research activities conducted online. Many online researchers are distressed at the manner in which some researchers abuse the internet as a means of collecting data. In particular, marketing research has been charged with engaging in deception, conflict of interest, violation of anonymity, invasion of privacy, data falsifications, dissemination of faulty research findings and the use of research as a guise to sell merchandise. It has been posited that when a researcher chooses to participate in unethical activities, that decision may be influenced by organisational factors. Therefore, a study using multiple regression analysis was designed to examine organisational factors as determinants of the incidence of unethical research practices. Six organisational variables were used as the independent variables, namely: extent of ethical problems within the organisation; top management actions on ethics; code of ethics; organisational rank; industry category; and organisational role. The participant’s evaluation of the incidence of unethical marketing research practices served as the dependent variable. Regression analysis of the data suggested that four of the six organisational variables influenced the extent of unethical research practice: extent of ethical problems within the organisation; top management actions on ethics; industry category; and organisational role. Thus, to reduce the incidence of unethical research practice, top management should take stern actions, clarify roles and responsibilities for ethical violations and address the extent of general ethical problems within the organisation.

To understand the role of quality and price in influencing the patronage of shoe shops, 14 major shoe shops in a large city were rated in terms of preference to shop, quality of shoes sold and price fairness. All the ratings were obtained on an 11-point scale, with higher numbers indicating more positive ratings.

a Run a multiple regression analysis explaining shoe shop preference in terms of shoe quality and price fairness.

b Interpret the partial regression coefficients.

c Determine the significance of the overall regression.

d Determine the significance of the partial regression coefficients.

e Do you think that multicollinearity is a problem in this case?
Why or why not?

In a survey pre-test, data were obtained from 20 participants on preference for boots () on a seven-point scale (1 = not preferred, 7 = greatly preferred). The participants also provided their evaluations of the boots on comfort (), style () and durability (), also on seven-point scales (1 = poor, 7 = excellent). The resulting data are given in the following table:

a Calculate the simple correlations between V1 and V4 and interpret the results.

b Run a bivariate regression with preference for boots (V1) as the dependent variable and evaluation on comfort (V2) as the independent variable. Interpret the results.

c Run a bivariate regression with preference for boots (V1) as the dependent variable and evaluation on style (V3) as the independent variable. Interpret the results.

d Run a bivariate regression with preference for boots (V1) as the dependent variable and evaluation on durability (V4) as the independent variable. Interpret the results.

e Run a multiple regression with preference for boots (V1) as the dependent variable and V2 to V4 as the independent variables. Interpret the results. Compare the coefficients for V2, V3 and V4 obtained in the bivariate and the multiple regressions.

Two-group discriminant analysis was used to assess the strength of each of five dimensions used in classifying individuals as TV users or non-users. The discriminant analysis procedure was appropriate for this use because of the nature of the predefined categorical groups (users and non-users) and the interval scales used to generate individual factor scores.
Two equal groups of 185 elderly consumers, users and non-users (total n = 370), were created. The discriminant equation for the analysis was estimated by using a subsample of 142 participants from the sample of 370. Of the remaining participants, 198 were used as a validation subsample in a cross-validation of the equation. Thirty participants were excluded from the analysis because of missing discriminant values.
The canonical correlation for the discriminant function was 0.4291, significant at the p
The cross-validation procedure using the discriminant function from the analysis sample gave support to the contention that the dimensions aided researchers in discriminating between users and non-users of TV. As the table shows, the discriminant function was successful in classifying 75.76% of the cases. This suggests that consideration of the identified dimensions will help marketers understand elderly consumers.
