Attitude. A learned predisposition to respond in a consistently favourable or unfavourable manner with respect to a given object.

Audit. A formal examination and verification of either how much of a product has sold at the store level (retail audit) or how much of a product has been withdrawn from warehouses and delivered to retailers (warehouse withdrawal audits).

Balanced scale. Scale using an equal number of favourable and unfavourable categories.

Banner. The variables that span the columns of the cross-tab; generally represents the subgroups being used in the analysis.

Before-after design. Experiment where a measurement is taken from respondents before they receive the experimental treatment condition; the experimental treatment is then introduced, and the post-treatment measurement is taken.

Before-after with control design. Experiment that adds a control group to the basic before-after design; the control group is never exposed to the experimental treatment.

Between-group variations. Between-group differences in scores for groups that were exposed to different treatments - represents "explained" variation.

Cartoon completion test. Projective technique that presents respondents with a cartoon of a particular situation and asks them to suggest the dialogue that one cartoon character might make in response to the comment(s) of another cartoon character.

Causality. Relationship where a change in one variable produces a change in another variable. One variable affects, influences, or determines some other variable.

Chi-square test statistic. Measure of the goodness of fit between the numbers observed in the sample and the numbers we should have seen in the sample, given the null hypothesis is true.

For instance, an experiment may be conducted where the price (independent variable) of a dozen boxed carnations is varied and the sales (dependent variable) is observed at each price set.

Internal secondary data. Data available within the organisation - for example, accounting records, management decision support systems, and sales records.

Interval data. Measurements that allow us to tell how far apart two or more objects are with respect to attributes and consequently to compare the difference between the numbers assigned. Because the interval data lack a natural or absolute origin, the absolute magnitude of the numbers cannot be compared.

Itemised (closed-ended) questions. Format in which the respondent is provided with numbers and/or predetermined descriptions and is asked to select the one that best describes his or her feelings.

Itemised rating scaling. The respondent is provided with a scale having numbers and/or brief descriptions associated with each category and asked to select one of the limited number of categories, ordered in terms of scale position, that best describes the object under study.

Laboratory experimental environment. Research environment constructed solely for the experiment. The experiment has direct control over most, if not all, of the crucial factors that might possibly affect the experimental outcome.

Likert scale. Scaling technique where a large number of items that are statements of belief or intention are generated. Each item is judged according to whether it reflects a favourable or unfavourable attitude toward the object in question. Respondents are then asked to rate the attitude towards the object on each scale item in terms of a five-point category labelled scale.

Line marking. Similarity judgements recorded by making a mark on a 5-inch line anchored by the phrases "exactly the same" and "completely different".

Line marking/continuous rating non-comparative scale. Procedure that instructs the respondent to assign a rating by placing a marker at the appropriate position on a line that best describes the object under study. There is no explicit standard for comparison.

Loaded questions. Questions that suggest what the answer should be or indicate the researcher's position on the issue under study.

Non-probability samples. Form of sampling where there is no way of determining exactly what the chance is of selecting any particular element or sampling unit into the sample.

Non-response error. Error that occurs because not all of the respondents included in the sample respond; in other words with non-response, the mean true value (on the variable of interest) of the sample respondents who do respond may be different from the entire sample's true mean value (on the variable of interest).

Non-sampling error. Degree to which the mean observed value (on the variable of interest) for the respondent of a particular sample agrees with the mean true value of the particular sample of respondents (on the variable of interest).
