Characteristics of the mode

The mode is the only measure of central tendency used with nominal variables.

Appropriate for each levels of measurement,

but not favored with continuous (interval-ratio) variables. Why?

Example of an ordinal variable (previously seen):

ISSP 20006, “Do you think it should or should not be the government’s responsibility to reduce income differences between the rich and the poor?”

The mode is the category...

  • “Definitely should be” in Hungary, and

  • “Probably should be” in the Czech Republic.

That is, the most commonly occurring categories differ in the two countries, Hungarians are more in favor of redistribution.

In some distributions there are two categories with the highest frequency. Such distributions are called bimodal.

Terminology: unimodal, bimodal, trimodal, multimodal.

Example: General Social Survey, 1991, USA.
