Step 1

Nominal scales are used, without any quantitative significance, to label variables. One might clearly call "labels" the "nominal" scales. A nominal scale represents a group attribute that doesn't have a normal order or rating.

The three basic central tendencies are mean, median and mode.

Step 2

According to the question, there are two nominal levels. it is a kind of categorical variable. Therefore, Mode will be best measure of central tendency for 2 nominal level variables because, the mode can be used for categorical data but it is not possible for the mean and the median. The mode may or may not exist, and the mode may have more than one value.
