Type/MMDI™ code conversion

This page enables you to produce an MMDI code from your type scores/knowledge, and vice versa. This may be useful if you want to produce your own MMDI report, eg: radar diagram, without completing the questionnaire.

Create MMDI code from type score

If you know your type scores, or the strength of your preferences, then you can create an MMDI code using the sliders, below right.

("-" scores)		("+" scores)
Move the sliders. You must enter a score for each preference otherwise the page will not provide you with a code.
Extraversion		Introversion
Sensing		Intuition
Thinking		Feeling
Judgment		Perception

Using your own knowledge

If you don't have scores from another type questionnaire, you can simply move the sliders to indicate the strength of your preference.

Using type scores

If you have the results of your questionnaire, such as the MBTI, JTI, TDI, Personality Profiler, etc., then the first step is to calculate your score as a percentage of the maximum score on that scale. This varies for different questionnaires, and can also depend on which version of form was used.

For example, MBTI Form G male maximum scores are: E: 51, and I: 57 (the maximum scores of the other dimensions vary and the female Form G has a different maximum score for F).

Therefore, if on the EI scale you scored E33, then 33/51 is 65%. You therefore move the EI slider (right) to -65. If on the EI scale you scored I27, then 27/57 is 47%, so you move the EI slider to +47.

The maximum scores of other versions of MBTI forms (eg: the UK Step I) may vary.

Create type score from MMDI code

Enter your MMDI code in the box and press submit.

Notes

Other type-based questionnaires may be measuring something different to the MMDI questionnaire. Eg: the MBTI aims to indicate 'clarity of preference', whereas the MMDI aims to indicate 'strength of preference'. Eg: if you are very clear that you have only a slight preference, then in theory your MBTI score should be high, but MMDI score low. In such circumstances the value of converting MBTI scores to an MMDI code or vice versa is dubious.

The scoring scales of the MMDI and other questionnaires are different. If you enter a type score to get an MMDI code, then enter your MMDI code to get a type score, you may get a different score back. This is due to rounding errors, and conversions of different scales based on slightly different theoretical principles.
