One matter that is always of concern, particularly in the latter situation, is reliability of measurement. Such studies are not really "panel research," as the fact that the data were gathered from a panel is incidental to the research. This paper reports on analysis of the published consumer behavior research using panels which appeared in 12 leading sources during the period 1975-1991. ABSTRACT - Consumer panels are now commonly used for longitudinal and cross-sectional studies of consumer behavior. Since panel studies are a special case of longitudinal research, respondents are typically conscious of their ongoing part in responding to the same or similar questions over a period of time. Panel Data Set B, on the other hand, would be considered an unbalanced panel as data does not exist for each person each year. First, because panels yield linked data on the same individuals on more than one occasion, the researcher can analyze the data in greater depth. Since quantitative outcomes were not combined in the present study, we have elected not to delete studies which may have some overlap.]. A panel door constructed with panels, usually shaped to a pattern, installed between the stiles and rails that form the outside frame of the door. TABLE 2 PANEL STUDIES BY PUBLICATION SOURCE AND CATEGORY Research Design Few published panel studies employ experimental or quasi-experimental designs. In our view, all panel studies should measure both dimensions of panel reliability. 11, 371-379. For an aesthetic look of the house, the panel door may be constructed with 4 panels or 6 panels. Specific characteristics or differences of the wine products are evaluated. The first issueChow to set up a panelCis covered quite well elsewhere. Panel members have restrictions on how often they can be contacted. Each study was examined to determine whether a panel was used simply as a subject pool for a one-shot survey. To the extent possible, members of an interview panel should be diverse and composed of individuals having various working relationships and interactions with the position. 5. These methods relate to types of designs (natural and quasi-experimental), procedures for implementation, and methods of selecting appropriate types of analyses, all of which vary greatly in use. One other advantage is that costs of doing research may be less than that using other approaches, particularly when a commercial panel organization is used. Even without these problems some panels per se may not be representative of any particular population, although it is possible to develop representative samples from the panel. Because maturation and history are such plausible causes (and/or threats to validity) in longitudinal studies, the researcher should be particularly concerned to assure that the instruments/measures are reliable. Although both uses, by definition, are based upon random error rather than systematic error and both refer to the generalizability of measurement, they are distinct. Finally, there is considerable information available on each panel. Moreover, the application of electronic and communications technology continues to encourage new types of panels, such as those involving advertising delivery via split-cable television and in-store scanner-recording of purchases. However, only the turnover table from the panel in (B) can tell us that 40 former buyers of Strong switched to X and that 80 former buyers of X switched to Strong. Panel members Panel members include members of the public (lay) and registered members of all the professions HCPC regulates.

(1982), "A Longitudinal Study of Television Advertising Effects," Journal of Consumer Research, 9 (December), 279-286. Of the 71 panel articles studied, only 12 (16.9%) involved some experimental manipulation. The Panel Members will participate in on-campus interviews and may be asked to participate in reference checking. Verification of product movement by examining physical records or performing inventory analysis are characteristics of which of the following types of syndicated services. Almost three-fourths of the studies used data from continuous panels, panels set up to collect data for a number of research studies. The intent of the present exposition is not to criticize past work using panels for consumer research. Therefore, those issues are not addressed in the present paper. Burnett, John J. and Julie Baker (1989), "The Robert-Worezel Hierarchical Model: An Extension Through Methodological and Variable Delineation Considerations," Proceedings, Educators' Conference of American Marketing Association, 265. All articles and papers published in 12 major journals or proceedings during the stated period were examined to identify studies suitable for inclusion in the present investigation. 2. To be included in the set for further analysis, a study had to meet three criteria. The remaining studies were further examined to determine whether the study employed a panel (or panels) or panel data principally to develop a measurement instrument or to test a model, whether the published report provided insufficient description of the panel to merit inclusion, or whether the study met specified criteria to qualify for further analysis. (1988), Marketing Research, 2nd ed. Nonetheless, significantly more needs to be done. A second approach involves a longer time for assessment. TABLE 1 CHANGE IN SALES FOR STRONG BETWEEN T1 AND T2 ADVANTAGES AND PROBLEMS ASSOCIATED WITH PANEL RESEARCH The repeated collection of data from consumer panels creates both opportunities and problems. 5. As a panel moderator, asking insightful and interesting questions is one of your biggest responsibilities. All have a bearing on measurement, which is of utmost importance and can complicate the analysis task (Wilson 1980, p. 231). Some persons interviewed at the first time may be unable or unwilling to be interviewed later on. One result of this investigation is an assessment of the state of the use of panel approach in published consumer behavior studies. The nature of panel data above is sufficient to argue that there is a concept of panel reliability. The panel, typically 3-4 experts or practitioners in the field, shares facts, offers opinions and responds to audience questions either through questions curated by the moderator or taken from the audience directly. Rogosa, David (1987), "Myths About Longitudinal Research," Stanford University, Center for Educational Research, Working Paper 87-CERAS-23. These studies were eliminated from further analysis, usually because their use of panel members as respondents was based on access, representativeness, and convenience, not on the use of the panel respondents as a panel with the same variables measured on more than one occasion. 2. The data in this study consist of published studies of substantive aspects of consumer behavior. David L. Sills, Macmillan and the Free Press, Vol. The term "panel research" can be applied to a wide variety of research. Churchill and Peter (1984) in a recent meta-analysis employed the following decision rule: "If any essentially identical study was reported in more than one publication, only the most current one was included in the investigation." Nicosia, Francesco M. (1965), "Panel Designs and Analyses in Marketing," in Marketing and Economic Development, ed. -Tom Webster, writer, speaker, and panel moderator. All have a bearing on measurement, which is of utmost importance and can complicate the analysis task (Wilson 1980, p. 231). Since such a small number of studies reported any type of reliability, it is not possible to generalize about the characteristics of such studies. Demographic characteristics include gender, generation, race and ethnicity, education, geographic region, and marital status. Attrition and mortality affect the representativeness of a panel. 11, 371-379. The data in this study consist of published studies of substantive aspects of consumer behavior. New York: Holt, Rinehart and Winston. In addition, a number of consumer product firms maintain their own consumer panels or create short-term "ad hoc" panels to test new products and promotional techniques. This means that the researchers had designed their study as panel research. Sudman and Ferber (1979, p. 1) note that "from a conceptual point of view, even two interviews on the same topic with the same respondent would qualify as a panel study. Ferber, Robert and Linda B. Lannom (1980), "Research Panels in Consumer Behavior," in Advances in Consumer Research, Vol. The next, and perhaps more important, question is how can the concept of panel reliability be operationally measured. In addition, research designs with two observations are usually inadequate for the study of individual growth and individual differences in growth; at best, two-wave designs permit studying individual differences in change or some type of average rate of change (Rogosa 1987, p. 9).
