That depends on the data.

mode
The measure of variability tells you how close to the central value the data values lie: that is whether the cluster is tightly packed around the central value of spread out over a large range of values.
The measure of central tendency that refers to the value that appears most frequently in a data set is the mode. It represents the data point with the highest frequency of occurrence.
The median.
Median is your answer
When the data are not numerical but can be ordered , the median may be used as a measure of central tendency. Put the data in order and choose the middle value. For example, low, medium,medium,low, high etc.
