A positive number represents increased interest as a result of exposure to that element.
A negative number means that element detracts from interest.
A number near zero means that element is unimportant in increasing interest.

Screen Shot

What is a good element score?

Each study has its own range of scores. The scores are relative to one another, with larger numbers indicating elements with greater impact (positive or negative). There is no absolute number, which is meaningful across all studies.
AS A VERY GENERAL RULE OF THUMB (which will vary with product category, element list, branded or unbranded study, innovative or traditional product, and so on):

Below -2: Avoid this element. It detracts from interest

Between -1 and +3: This element is broadly neutral. It does not greatly impact interest.

Between +4 and +7: Solid but not inspired

Over +7: Strongly motivating. Probably important.

Studies, which include a wide range of scores, indicate that it makes a difference to the consumer what you say, and how you say it.
Studies, which have more neutral scores, may have higher constants, variations between subgroups, or a wider selection of acceptable alternatives within the middle range.

Are there always positive and negative scores?

NO, NOT ALWAYS!

Some studies have few negatives.

The idea/concepts/elements chosen are all powerful. It may be a novel idea, or it may be the language chosen, but whether the reason is conceptual or exceptional it is always good to have a choice of only positives.

Some studies have few positives.

This often accompanies a high constant. This implies there is a large downside risk in communication, and very little to gain.

How do I interpret the constant?

The constant reflects the level of interest not attributable to the individual elements.

It is the level of interest driven by in-going forces such as mindset towards the brand or category, reaction to the positioning statement, etc.
Ultimately, we would like the constant to approach zero, explaining as much of the interest as possible via the elements.

Constants are added to the element score to estimate total interest in a given concept.

High constants mean that the tested elements play a small role in motivating interest.

Very high constants are often found in heavily branded studies with well-known products. Consumers bring a great deal of background with them.
Very high constants are often found with lower element scores. There is less freedom for the elements to work.

Low constants mean that among that particular target, the skillful use of motivating elements is critical in developing interest. There may be a greater opportunity for elements to work.

Very low constants are sometimes found in unfamiliar products or ideas, where consumers need information from the elements to form an opinion.

Constants are specific to an individual study, and an individual element set, not general for products or categories.

However, as a BROAD GENERALIZATION, a constant between 40 and 50 is unremarkable.

How do I interpret the Classification Distribution?

By clicking Distribution at the top of the screen, you can get an instant classification distribution for the total panel of respondents.

Double click on the file (Windows Explorer).
Use a program such as Winzip to extract your data files.

Screen Shot

What are the files I get?

Below is an explanation of the data files you get:

.CLS - Classification:

This file contains data from the Classification part of the project. UID is a unique respondent's ID maintained by database. Do not pay attention to values in this column (there may be skips, etc.) This just a way for you to identify corresponding rows in different files if you need.

Qi - Question Number:

There is one column for Single Selection and Range questions. There is NO column for Description "questions". For Multiple Selection Questions the columns are labeled as Qn_Mm where n is question number and m is option number in this question.

.ELM - Element List:

This file contains a list of all of the elements in the project. Note - These element key codes (E_1, etc.) are used in other files (.op0, .opc, .ot0, .otc) as column headers to identify utility values for each element.

.OP0 - Persuasion Model:

This file contains individual scores for each of the respondents by each element. The 1...9 Ratings have been recorded as 11, 22, 33, 44, 55, 66, 77, 88, 100 before running the regression (see on-line help). Const. is the constant for the regression. See Help file on How to read this data.

.OPC - Combined Persuasion Model & Classification File:

This file is the aggregation of the .OP0 and .CLS files. This file is provided for your convenience and is redundant. By merging .OP0 and .CLS, we created a file that is easier to use if you want to create subgroups or just analyze data based on classification questions.

.OPEN:

This file contains combined data for open ended questions from the classification questionnaire (one line per respondent).

.OT0 - Interest Model:

This File contains individual scores for each of the respondents by each element. Before running the regression, ratings between 1 and 6 are recorded as 0 and ratings 7, 8 and 9 are recorded as 100 (see on-line help) where Const. is the constant for the regression. See Help file on How to read this data.

.OTC - Combined Interest and Classification Model:

This file is the aggregation of the .OT0 and .CLS files. This file is provided for your convenience and is redundant. By merging .OT0 and .CLS, we created a file that is easier to use if you want to create subgroups or just analyze data based on classification questions.

.QSN - Classification Questionnaire:

This file lists all classification questions asked in the project.

.QST - Rating Question:

This file contains the question asked during the concept portion of the survey.

How do I find a viable source of respondents?

There are many sources of potential respondents on the Internet:

Professionally managed online panels
Opt-in databases
Client-provided email address lists
Websites

Which source to use largely depends on the specifics of the sample that is desired.

If the sample calls for a general population of Internet users, both general population email lists and general interest online panels can deliver respondents to the survey at a reasonable cost.

General population email lists usually pull lower response rates but can be very cheap - as long as people respond in sufficient numbers.
Online panels offer the benefit of committed respondents and high response rates but can be relatively expensive.

If the target sample is low incidence, a more targeted approach is usually required.

Potential sources of respondents include special interest online panels, special interest email lists, and Websites whose visitors match the profile of the desired sample.

How do I get people to participate in online surveys (recruiting)?

Once a promising source of potential respondents has been identified, a suitable recruitment strategy must be implemented.

Respondents from online panels, opt-in databases and client provided email address lists are usually recruited via email invitation.

The invitation should position the study topic as one of interest to potential respondents and explain why participation is important.
It should be brief and to the point; it should not require any scrolling.
Whatever incentive is offered should be mentioned as early as possible, possibly in the subject line.
Incentives can take several forms, of which some of the most popular are prize drawings (which are relatively cost-effective and easy to administer), coupons redeemable at online retailers, cash payments from online banks, and other, more traditional premiums such as magazine subscriptions and pre-paid phone cards.

Recruitment at websites, an approach known as Website intercept, can be very effective in recruiting low incidence samples.

This approach relies on a close match between the characteristics of the target sample and the selected Website’s typical visitor profile.
Various techniques can be used, including banner ads and pop-up windows.

How do I screen respondents (verify that the right people are participating)?

Extra care must be taken in selecting the source of respondents to ensure that most of those invited actually qualify for participation.

The wording of the invitation or pop-up window can also specify respondent criteria (e.g. “Are you a current user of XYZ? If so, then you’ll love our new interactive survey.”)

How do I avoid high drop-off rates (make sure people complete the survey)?

Several variables influence the drop-off rate (the percentage of respondents who log in to a survey but fail to complete it).

Number of screens
Length of time needed to complete the survey
The perceived value of incentives
The overall difficulty of the survey (including the likelihood that respondents will find it confusing, a common complaint about IdeaMap).
The source of respondents may also play a role.
