What do shoppers notice? How do they go through a store? Mystery Shoppers — This involves hiring a regular person to go into a store and pretend to be an everyday shopper. They will then report on aspects of their experience, such as store cleanliness, politeness of staff, etc. In the case, the mystery shopper is the researcher and the store is the subject being observed.

Previous post Quantitative vs. Next post Data Types in Statistics. A little later a promotional campaign was launched within the test area and after a period of time the sample of farmers were again visited and asked to identify the brands of seed with which they were familiar. It is likely that any increase in awareness of the company's brand was due, in part at least, to the heightened awareness of issues relating to seeds caused by the pretest activity. That is, the pretest is likely to increase interest in matters relating to seeds and therefore make farmers more attentive to the brand promotion than they otherwise might be.

Experiments requiring the cooperation of respondents over a substantial period of time are most likely to suffer from maturation effects. Consumer and farmer panels are examples of experimental instruments that demand longer term participation by panel members. Suppose that a farmer panel were established to measure the level of adoption of new marketing practices or technologies promoted by agricultural extension officers. As the years pass the marketing extension officer has noted that farmers on the panel appear to be adopting fewer of the innovations being proposed by the extension service.

However, the lower rates of adoption may not be explained by either the marketing extension service becoming less effective in communicating the benefits of innovative marketing practices and technologies nor by current innovations being somehow less appropriate or offering more marginal benefits. Rather, the explanation may be that the panel itself is aging and as farmers get older they may become more resistant to change. Certainly as people get older their needs and attitudes are subject to change. In these circumstances the data drawn from the panel is a function of the maturation of the panel rather than the experimental variables i.

Whilst it is not always possible to adjust the experimental design so as to eliminate each of these potential threats to the validity of results, it is always possible to measure their impact upon results.

Experimental design in marketing research

The chief device for doing so is to include a 'control group'. Instrumentation: From time to time, measurement instruments have to be recalibrated or their readings become suspect. Although marketing research does make use of a wide range of mechanical, electrical and electronic instruments in experiments that clearly require periodic readjustment, e.

Questionnaires may contain standardised questions with the challenge to consistency coming from the interpretation of the meaning of the question.

General Structure and Writing Style

Consider the apparently straight-forward question, "How big is your farm? The variation is due to farmers' interpretation of what the researcher really wants to know. Some farmers will include only the land area that they had under crop in the year of the survey whilst others will include both productive and nonproductive land. In other instances, farmers may understand the question to mean the area of land they actually own. Another aspect is that of consistency in the conduct of interviews. There can be variation in the data collected during an experiment if either different interviewers are used to collect data after the experiment from those who conducted interviews before the experiment; or interviewers change the way questions are put to participants as they become more familiar with the content of the questionnaire.

Mortality: Over time there is a danger that some participants will drop out of an experiment. This can happen when people literally die or decide withdraw from an experimental group for one reason or another. This obviously changes the composition of the experimental group. Where the effects of a marketing variable are being studied by comparing data drawn either from two groups that have been matched to ensure that their composition is identical or the same group at different points in time then mortality can confound the results.

Sampling bias: Sampling bias occurs when the method of assigning participants to experimental groups results in groups whose behaviour cannot be compared to one another because they differ in some important respect s. Consider the task of evaluating the implementation of new weighing and grading practices within a municipal grain market. It could be that it is easier for larger grain traders to adopt the new practices since they are better able to afford the grading and weighing equipment required.

If during a field experiment conducted to study the rate of adoption two groups are established with a view to comparing the rate of adoption within them and one of those groups is predominantly comprised of larger or smaller traders then this is likely to distort the results. External validity Interactive effects of testing: The design of the experiment itself may give rise to measurement variations between the "before" and "after" phases of the research. Consider a test of consumer acceptance involving two exotic rice varieties being evaluated as possible replacements for a popular indigenous variety which is suffering from a disease and is therefore in short supply.

The experimental design involves leaving a trial pack of rice A with a sample of households and returning a few weeks later to interview members of the household about rice A and to deliver a second trial pack containing rice B. A third visit is subsequently made during which household members are asked questions about rice B. Respondents' assessment of rice B is not made under the same conditions as their assessment of rice A. When trying rice A the respondents are likely to have made comparisons, perhaps only subconsciously, with existing rice varieties that they already use.

However, when evaluating rice B the respondents will also be making comparisons with rice A. This problem can be overcome, to some extent, by splitting the sample so that half are given the trial varieties in the order rice A then rice B; the remaining half are given the two varieties in the reverse order of rice B then rice A. A more difficult problem to overcome is that whatever the sequence of presentation, by the time household members are asked about the second trial variety, they have become more 'experienced' interviewees and respond differently simply because they feel they better understand what the interviewer wants and how to answer the questions.

By the same measure, the interviewer becomes more experienced the second time around, having become more familiar with the product, the interviewing process, and the questionnaire or interview schedule , and may pose the questions in a different way. As a result, the interviewer may elicit different information on the third call from that which was obtained on the second visit. Interactive effects of sampling bias: It can happen that participants are assigned to an experimental group without due concern for possible bias and this then interacts with the experimental treatment producing a spurious outcome.

Such an interactive sampling bias would result from unknowingly assigning heavy users of a particular product category to one experimental group and using favourable responses to a new formulation within the category as the basis for projecting national demand. Contrived situations: Any laboratory experiment is, by definition, unlike the real world.

On occasion this leads to experimental results which are not replicated in the real world. An outstanding example of this set of circumstances is that of Coca Cola's infamous blind taste panels. Coca Cola was concerned at the creeping increases in market share of Coke's main competitor Pepsi. Coca Cola decided to conduct sensory analysis tests where participants were asked to score two colas on taste preference. The participants were given the colas in unmarked cups i. On balance, the preference was of Pepsi's slightly sweeter cola.

Coca Cola reacted in a way seldom seen anywhere in the world. The brand leader was removed from the market and a new, slightly sweeter formulation was launched under the Coca Cola brand name. It was to prove a costly mistake. Coca Cola were inundated by calls from consumers who were irate over the company's tampering with a product that has almost become a national institution. Most Americans have grown up with Coca Cola and could not accept that it could be changed.

The company was forced to reintroduce the original formulation under the title of Coke Classic. Coca Cola's taste panels were conducted in an artificial environment in which such variables as the brand name, the packaging and all the associations which go along with these were not allowed to operate.

The research focused only on the taste characteristics of the product and a particular result was obtained. However, in the real world people consume Coca Cola for many reasons, many of them having little to do with the taste. Experimental designs The process of experimentation is one of subjecting participants e.

This is a common approach in advertising research where a sample of target customers are interviewed following exposure to an advertisement and their recall of the product, brand, or sales features is measured. The amount of information recalled by the sample is taken as an indication of the effectiveness of the advertisement.

For example, marketing extension personnel might have completed a trial campaign to persuade small-scale poultry producers, in a localised area, to make use of better quality feeds in order to improve the marketability and price of the end product. The decision to extend the campaign to other districts will depend on the results of this trial. After-only measures are taken, following the campaign, by checking poultry feed sales with merchants operating within the area. Suppose a rise in sales of good quality poultry feed mixes occurs four weeks after the campaign ends.

It would be dangerous to assume that this sales increase is wholly due to the work of the marketing extension officers. A large part of the increase may be due to other factors such as promotional activity on the part of feed manufacturers and merchants who took advantage of the campaign, of which they were forewarned, and timed their marketing programme to coincide with the extension campaign.

If the extension service erroneously drew the conclusion that the sales increase was entirely due to their own promotional activity, then they might be misled into repeating the same campaign in other areas where there would not necessarily be the same response from feed manufacturers and merchants. After-only designs are not true experiments since little or no control is exercised over any of the variables by the researcher. However its inclusion here serves to underline the need for more complex designs. The before-after design is an improvement upon the after-only design, in that the effect of the independent variable, if any, is established by observing differences between the value of the dependent variable before and after the experiment. Nonetheless, before-after designs still have a number of weaknesses. The packer is considering doing so in response to complaints from commissioning agents that the present packaging affords little protection to produce from handling damage.

The packer wants to be sure that the economics of switching to plastic crates makes sense. Therefore, the packer introduces the plastic crates for a trial period. Unless prices increase by more than the additional cost of plastic crates then there is no economic advantage to using the more expensive packaging.

However, there are several equally plausible explanations for the upward drift in produce prices including a shortfall in supply, a fall in the quality of produce supplied by competitors who operate in areas suffering adverse weather conditions, random fluctuation in prices, etc. Marketing experimentation is a research method which can be defined as "the act of conducting such an investigation or test". Marketing experimentation is commonly used to find the best method for maximizing revenues [3] [4] through the acquisition of new customers. For example; two groups of customers are exposed to different advertising test.

How did consumers react to advertising compared to the other group?

Did the advertising increase sales for each group? To gain an accurate result from experiments, the experimenter must consider outside factors that could effect the dependent variable. Continuing from the advertising example above; did sales increase because of a festive seasons at that particular time.
